Answer:

enthalpy

Explanation:

If it is used with a triangle in front, (delta H), that means the change in enthalpy. Delta H= (m)(s)(Delta T).  m=mass of products, s=heat of the products, Delta T = change in temperature.

Hope that helps

A gas cylinder contains 2.0 mol of gas X and 6.0 mol of gas Y at a total pressure of 2.1 atm. What is the partial pressure of ga
liubo4ka [24]
1) mol fraction of gas X= 2/(6+2)=2/8=1/4
2) mol fraction of gas Y= 6/(6+2)=6/8=3/4
3) Partial pressure of X = 1/4*2.1 atm=0.53 atm
4) Partial pressure of Y = 3/4*2.1=1.6 atm

A student makes a compound of sulfur and oxygen. She uses 5.00 g of sulfur and 4.99 g of oxygen, and all of the elemental substa
victus00 [196]
First, we apply the law of conservation of mass which states that the total mass in a system remains constant.
Therefore, there must be 5.00 g of sulfur and 4.99 g of oxygen in the product. Now, we determine the mass percentage using:

Mass % = (mass of sulfur x 100) / total mass of compound

Mass % = (5 * 100) / (5 + 4.99)

Mass % = 50.05%

The product contains 50.05% sulfur by mass.

If two gases are present in a container, the total pressure in the container is equal to
qwelly [4]

Answer: sum of the pressure of the two gases present.

Explanation:

According to Dalton's law, the total pressure of a mixture of gases is the sum of individual pressures exerted by the constituent gases.

p_{total}=p_A+p_B

For example if there are there are two gases hydrogen and oxygen with individual pressure of 30 and 20 atm each. Then the total pressure in the container will be:

p_{total}=p_{H_2}+p_{O_2}

Thus p_{total|=30atm+20atm

p_{total}=50atm

Thus if two gases are present in a container, the total pressure in the container is equal to sum of the pressure of the two gases present.
