8.3 kg, 1.7 Kg/cm3
-> ? cm3
Answer:
4.9 cm³
Explanation:
Given data:
Mass value = 8.3 kg
Density = 1.7 kg/cm³
Volume = ?
Solution;
In given question from the units we got to know that the mass and density value is given and we have to calculate the volume.
Thus, we will apply density formula.
Density = mass/ volume
d = m/v
1.7 kg/cm³ = 8.3 kg/ v
v = 8.3 kg/ 1.7 kg/cm³
v = 4.9 cm³
Thus, the volume is 4.9 cm³.

How many atoms are in 0.075 mol of titanium?
O 4.5 x 1022
O 1.2 x 10-25
O 6.4 x 102
O 2.2 x 1024
Answer:
The answer is
4.5 × 10²²Explanation:
To find the number of atoms of titanium , given it's number of moles we use the formula
N = n × Lwhere n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question
n = 0.075 mol
We have
N = 0.075 × 6.02 × 10²³
We have the final answer as
4.5 × 10²²Hope this helps you
Find the speed of the ATV that goes 60 miles in 2 hours._______________________ m/hr
Given parameters:
Distance of ATV = 60miles
Time = 2hrs
Unknown:
Speed = ?
Solution:
Speed is a scalar quantity. It has magnitude but no direction. Mathematically, speed is distance divided by time.
Speed = [tex]\frac{distance}{time}[/tex]
Input the parameters;
Speed = [tex]\frac{60}{2}[/tex] = 30miles/hr
The speed of the ATV is 30miles/hr
are we made of star dust? why or why not
Answer: Technically, yes. Are bodies are primarily made of carbon, which is found in pretty much everything. Stars, planets, plants, etc.
Explanation:
1.04 x 10^-3 pm to mm
Answer:
1 pm = 10^-12 m = 10^-10 cm = 10^-9 mm
1.04 x 10^-3 pm = 1.04 x 10^-3 x 10^-9
= 1.04 x 10^-12 mm.

If the approximate density of 6.5 L of ethanol is 0.79 g/ mL, what is the mass in grams?
Answer:
The answer is 5135 gExplanation:
The mass of a substance when given the density and volume can be found by using the formula
mass = Density × volumeFrom the question
density = 0.79 g/mL
1 L = 1000 mL
6.5 L = 6500 mL
We have
mass = 0.79 × 6500
We have the final answer as
5135 gHope this helps you
How many joules are needed to melt 50 g of ice at 0°C?
Answer:
You need the Delta H fusion for water. Multiply that by 50 grams. Then multiply 50 g x 4.184 x 65 to get joules to raise water to 65 degrees. Add these values together to get total joules.

You have decided to bake a cake. You mix all of your ingredients together to make a delicious chocolate cake. Then, you bake your cake at 350 degrees fahrenheit. You have to perform both a physical and a chemical change to bake a cake. What is the chemical change? Include at least 2 pieces of evidence or indicators to explain how you know it was a chemical change.
Answer:
A gas is evolved
The ingredients can not be recovered
Explanation:
A chemical change is one in which a new substance is formed and it is not easily reversible.
One major ingredient used in cake baking is the baking powder or baking soda.
Baking a cake can be viewed as a chemical change. This is because, when the baking powder or soda is added in the presence of yeast, carbon dioxide gas is evolved as tiny bubbles of gas which makes the cake light and fluffy. Heat is equally given off in the process. The baking powder and other cake ingredients can not be recovered, hence, we can conclusively assert that a chemical change has taken place.

Answer:
balanced;
unbalanced;
unbalanced;
balanced;
Explanation:
CaO + 3C → CaC2 + CO //all elements are balanced
Na + H2O → 2NaOH + H2 //Na is not balanced on the left
4Fe + O2 → 2Fe2O3 //O is not balanced on the left
