Answer:
The chemical reaction between the citric acid and sodium bicarbonate
Explanation:
Does anyone knows how to solve this??
Answer:
²⁴³₉₅Am --> ²³⁹₉₃Np + ⁴₂He
Explanation:
In alpha decay;
The mass number decreases by 4
Atomic Number decreases by 2
Mass Number = 243 - 4 = 239
Atomic Number = 95 - 2 =93
Element = Neptunium (Np)
Equation for the decay is given as;

how many atoms in 10.0 g of Ar?
Answer:
1.51 x 10^23 atoms of Ar
Explanation:
Start out with what you're given.
10.0 g of Ar/1 * 1 mol/39.948 g Ar * 6.022*10^23 atoms/1 mol
(It's easier if you write it out.)
You always want to start out w/ what you're given and continue your unit conversions from there. Since you started out with grams of Argon, you want grams of Argon on the bottom to cancel it out. Once you found the unit conversion: 1 mol/39.948 g Ar (molar mass of Ar), now it's time to convert to atoms. Since 1 mol is up on top, put 1 mol on the bottom. Considering you're looking for atoms, use Avagradro's number: 6.022*10^23.
Once simplified, you should get 1.51 x 10^23 atoms of Ar.
***I hope this helps! I also suggest using a mole map, if you're interested.***

The atoms of the reactants unbond, rearrange and then rebond to form the products
Some atoms disappear while others multiply to form the products
The atoms of the reactants always stay together to form the products
New atoms are formed which combine to make the products
Answer:
A) The atoms of the reactants unbond, rearrange and then rebond to form the products
Explanation:
Using method of elimination:
A) The atoms of the reactants unbond, rearrange and then rebond to form the products
This is the correct option. Chemical reactions involves breaking and forming of new bonds.
B) Some atoms disappear while others multiply to form the products
This option is incorrect. Atoms do not disappear
C) The atoms of the reactants always stay together to form the products
This option is incorrect. The bonds between the atoms in the reactants must first be broken before products can be formed.
D) New atoms are formed which combine to make the products
This option is incorrect. Atoms do not just form out of nowhere.
White arctic hares blending in with the white snow in their environment is an example of what type of camouflage?
A. hiding
B. protective resemblance
C. mimicry
D. protective coloration
Answer:
The answer to your question is A.
D. Protective coloration. Protective coloration, also known as "crypsis," is a defense mechanism used by animals to avoid detection by predators or prey.
An illustration of protective coloration, which is a sort of camouflage, is how white arctic hares blend in with the white snow around them. Animals use protective coloration, commonly referred to as "crypsis," as a defensive strategy to evade being seen by predators or prey.
In this instance, the white arctic hares' fur is the same shade as that of their snowy environment. Their chances of survival are increased by this merging, which enables them to remain unnoticed and effectively hidden from predators like polar foxes or birds of prey. They have a better chance of escaping or avoiding detection when they are well-camouflaged, making it difficult for predators to see them against the white background.

Explanation:
A student pushes a box with a force of 20 N to the right and another student pushes the box with a force of 5 N to the left.
What is the net force and direction in which the box moved?
The net force acting on the box is 15 N which is the difference of the two acting forces and the box shifts to the right in the direction in which greater amount of force is applied.
What is force?Force is defined as a cause which is capable of changing the motion of an object. It can cause an object which has mass to change it's velocity. It is also simply a push or a pull . It has both magnitude as well as direction.Hence, it is a vector quantity.
It has SI units of Newton and is represented by'F'.Newton's second law states that force which acts on an object is equal to momentum which changes with time. If mass of object is constant, acceleration is directly proportional to net force acting on an object.
The concepts which related to force are thrust and torque .Thrust increases the velocity of an object and torque produces change in rotational speed of an object.

Determine the percent yield for the reaction between 98.7 g of
Sb2S3 and excess oxygen gas if 72.4 g of Sb4O6 is recovered along with an unknown amount of sulfur dioxide.
The percent yield of the reaction would be 85.64%
Percent YieldFrom the balanced equation of the reaction:
[tex]9 O_2 + 2 Sb_2S_3 ---> 6 SO_2 + Sb_4O_6[/tex]
Mole ratio of Sb2S3 to Sb4O6 is 2:1
Mole of 98.7g Sb2S3 = 98.7/339.7
= 0.29 moles
Equivalent mole of Sb4O6 = 0.29/2
= 0.145 moles
Mass of 0.145 Sb4O6 = 0.145 x 583
= 84.535 g
Percent yield = yield/theoretical yield x 100
= 72.4/84.535 x 100
= 85.64%
