12.0 g NaHSO4 (MM: 120.1 g/mol) is dissolved in water to make a 2.00 L solution. What is the molarity of the resulting NaHSO4 solution?
Answers
Answer:
0.05 M
Explanation:
First we convert 12 g of NaHSO₄ into moles, using the given molar mass:
12 g NaHSO₄ ÷ 120.1 g/mol = 0.10 mol NaHSO₄We can now calculate the molarity of the resulting solution, using the calculated number of moles and the given volume:
Molarity = moles / litersMolarity = 0.10 mol / 2.00 L = 0.05 MAnswer:
The molarity of the resulting NaHSO₄ solution is 0.05 [tex]\frac{moles}{liter}[/tex]
Explanation:
Molarity or Molar Concentration is the number of moles of solute that are dissolved in a certain volume.
The molarity of a solution is calculated by dividing the moles of the solute by the volume of the solution:
[tex]Molarity=\frac{moles of solute}{volume}[/tex]
Molarity is expressed in units [tex]\frac{moles}{liter}[/tex].
Molar mass is the amount of mass that a substance contains in one mole. Being the molar mass of the compound NaHSO₄ equal to 120.1 g/mole, then the number of moles that 12 grams contain is calculated by:
[tex]12 g*\frac{1 mole}{120.1 g} = 0.1 moles[/tex]
And being 2 L the volume of the solution, then replacing in the definition of molarity you get:
[tex]Molarity=\frac{0.1 moles}{2 L}[/tex]
Molarity= 0.05 [tex]\frac{moles}{liter}[/tex]
The molarity of the resulting NaHSO₄ solution is 0.05 [tex]\frac{moles}{liter}[/tex]
Work out the empirical formula of a compound that contains 35% of nitrogen , 5% of hydrogen and 60% of oxygen.
Answers
Answer:
[tex]H_5N_5O_6[/tex]
Explanation:
Hello there!
In this case, for the determination of empirical formulas, it is firstly necessary to assume the given percentages of the constituent atoms as the masses so we can compute their moles in the formula:
[tex]n_N=\frac{35gN}{14.01g/mol} =2.5molN\\\\n_H=\frac{5g}{1.01 g/mol}=5molH\\\\n_O=\frac{60g}{16 g/mol} =3molO[/tex]
Thus, we need to divide the resulting moles, by the fewest ones (those of nitrogen) in order to determine the coefficients in the formula:
[tex]N:\frac{2.5}{2.5}=1\\\\H:\frac{5}{2.5}=2\\\\O:\frac{3}{2.5} =1.2[/tex]
However, we need to turn all these numbers, whole numbers, so we multiply by 5 to get:
[tex]H_5N_5O_6[/tex]

In the atmosphere, it is more common to find two oxygen molecules joined together than to find a single atom of oxygen. Why? What would that molecule look like? What would this molecule be called?
Answers
Answer:
See explanation
Explanation:
Oxygen has six electrons in its outermost shell. This means that its octet can be completed when it shares two electrons with another oxygen atom.
In a covalent bond, each bonding atom contributes one electron to the bond. This means that four electrons are shared between two oxygen atoms. Each atom contributes a total of two electrons which are shared. This molecule of oxygen satisfies the octet rule rather than a single atom of oxygen.
An image of the oxygen molecule is attached to this answer.
This system of two oxygen atoms joined together in a covalent bond is called an oxygen molecule(O2).

We want to find the number of magnesium atoms. We can see that there is a subscript of 3 after the magnesium, so there are 3 magnesium atoms in 1 molecule of the compound.
However, there is a subscript of 4 that comes after the entire compound, so there are actually 4 molecules, with each molecule containing 3 magnesium atoms. Multiply 4 and 3.
3 Mg * 4 = 12 MgThere are 12 magnesium atoms.

A DAY IN THE LIFE OF METIS JOURNAL. I WROTE IT HOPE U LIKE IT XD
We, who live in the west, were Nomadic. So we always moved from place to place to hunt buffalo and other fur-bearing animals. And now again we have to shift everything we collected , like, all the essential needs we collected. It’s really hard to shift stuff, But when you move to a new place you get to see new beautiful places. They are just so satisfying to see! It’s like all my work(like the shifting work) is paid off. I love it! We always meet the Hudson’s bay company employees, and give them furs which we took from the bissons and other furry animals we hunted. And in exchange they give us their (Hudson’s Bay company) goods. Which is good! Because then we or I won't be able to enjoy that delicious pemmican!
The one reason that makes me proud of my parents is that because of them I am like a translator for both sides in the fur trade! Anyways coming back to the present. As I said before, we were moving today to another place, But on the way some people along with my father will ride the famous York boats carrying supplies to fur posts. I begged my father to take me with him! And as usual he gave me some silly reason for me to stay. And now since I don’t have anything to do I will-..Nevermind, My mom’s calling me. Okay after helping my mom keep the fur posts into the York boats me , my mom, and the others are just relaxing and enjoying nature just to take a break. Since, I am so obsessed with my Journal notebook today I’m just going to sit here and right what comes to my mind. I’m not like the others who always seem to be talking with someone. I like my own space!
I kind of miss my dad already, but he and his fellow members need to travel the waterways from the red river further west and north to hudson bay. These red river carts also travel the trek back and forth over land to St. Paul, Minnesota and to posts in saskatchewan. Speaking about the red river, the only large settlement in the region is the red colony. About 12000 people lived in this colony around Fort Garry. Some were the original Selkirk settlers or their descendents. They had come from Scotland with lord Selkirk when he established the colony in 1811. Many of these original settlers were poor farmers who had been displaced from their lands in scotland. They had endured many hardships in the early years of settlement, including foods, hunger, and sickness. I love studying about other colonies, cultures , history etc.
2. What happens to the temperature of air when it is compressed?
Answers
Explanation:
the pressure and temperature of the air increase
reason:
the volume of the space containing air decreases.
Explanation:
Whether you know it or not, compressed air is involved in every aspect of our lives, from the balloons at your birthday party to the air in the tires of our cars and bicycles. It was probably even used when making the phone, tablet or computer you’re viewing this on.
The main ingredient of compressed air is - you guessed it! - air. Air is a gas mixture, which means it consists of many different gases. Primarily these are nitrogen (78%) and oxygen (21%).
The temperature of the air is directly proportional to the mean kinetic energy of these molecules. This means that the air temperature will be high if the mean kinetic energy is large (and the air molecules move faster). The temperature will be low when the kinetic energy is small.
Compressing the air makes the molecules move more rapidly, which increases the temperature. This phenomenon is called “heat of compression”. Compressing air is literally to force it into a smaller space and as a result bringing the molecules closer to each other. The energy that gets released when doing this is equal to the energy required to force the air into the smaller space. In other words, it stores the energy for future use.

good answer and you get brainliest
Answers
Answer: D: plutonium-239
Explanation: Got it right on the quiz
The table below shows a list of radioisotopes and their half-lives.
A 2-columns table with 10 rows. Column 1 is labeled radioisotope. Column 2 is labeled half-life. Lithium-5, 3 × 10⁻²² seconds; polonium-211, 0.516 seconds; Barium-139, 82.7 minutes; uranium-240, 14.1 hours; Bismuth-210, 5.012 days; uranium 232, 68.9 years; carbon-14, 5730 years; plutonium-239, 24,065 years; beryllium-10, 1.6 × 10⁵ years; uranium-238, 4.5 times 10 to the 9 years.
The radioisotope that has the longest half-life is the best to use in powering planet and space exploration vehicles because they can travel farther. The radioisotope is the best to use is:
d) plutonium-239
Plutonium-239 has the longest half-life of all the radioisotopes listed, at 24,065 years. This means that it will take 24,065 years for half of the plutonium-239 in a sample to decay. This makes it a good choice for powering planet and space exploration vehicles because it will last for a long time.
The other radioisotopes listed have much shorter half-lives. Lithium-5 has a half-life of 3 × 10⁻²² seconds, polonium-211 has a half-life of 0.516 seconds, barium-139 has a half-life of 82.7 minutes, uranium-240 has a half-life of 14.1 hours, bismuth-210 has a half-life of 5.012 days, uranium-232 has a half-life of 68.9 years, carbon-14 has a half-life of 5,730 years, and beryllium-10 has a half-life of 1.6 × 10⁵ years.
So, the best radioisotope to use for powering planet and space exploration vehicles is plutonium-239. It has the longest half-life, which means that it will last for a long time and provide a steady source of power.

Balance the oxygens first. What do you need to multiply by to get to a common multiple of 2 and 3 to balance the oxygens? The common multiple is 6, so multiply the O2 by 3 and the Al2O3 by 2.
Al(s) + 3O2(g) —> 2Al2O3(s)
Now balance your aluminum. You have 1 in the reactants and 4 in the products, so multiply the reactant by 4.
