Answer: D=4.35g/L
Explanation:
The formula for density is 
. M is mass in grams and V is volume in liters.
Since we are give pressure and temperature, we can use the ideal gas law to find moles/volume. FInding moles/volume would give us the base for density. All we would have to do is convert moles to grams.
Ideal Gas Law: PV=nRT
Now that we have moles, we can use molar mass of chlorine gas to find grams.
With our grams, we can find our density.
We need correct significant figures so our density is:
Answer:
Now "q" is the heat and energy is the capacity of any object or body ton perform any work. So we can relate them if we take the term specific heat in consideration.
As specific heat is the the amount of heat required to raise the temperature of an object in specific from one degree Celsius, for ice it is 2.108 kJ/kgK.
Explanation:
- c = specific heat capacity,
- ΔT = change in temperature
So, we have:
- It is the ratio of the amount of heat energy transferred to an object to the resulting increase in temperature of the object.
Answer:
superstition
Explanation:
Because there is no scientific reason behind it and no connection of it to science.
Get the molarity we need to divide the number of moles of NaCl by the volume of the solution. So, 0.32 moles NaCl divided by 3.4 L, and that gives 0.094 M NaCl.
Answer:- B: 
is the right answer.
Solution:- The balanced equation is:
We have been given with 8.75 grams of oxygen and asked to calculate the grams of hydrogen needed to react with given grams of oxygen according to the balanced equation.
From balanced equation, 1 mole of oxygen reacts with 2 moles of hydrogen.
So, let's convert grams of oxygen to moles and multiply it by the mole ratio to calculate the moles of hydrogen that are easily converted to grams on multiplying by it's molar mass.
The complete set up looks as:
=
Hence, the right option is B: .
