Answer:
Weatherization or weatherproofing is the practice of protecting a building and its interior from the elements, particularly from sunlight, precipitation, and wind, and of modifying a building to reduce energy consumption and optimize energy efficiency.
Answer:
A 0.239mol
Explanation:
From the equation:
We were given that 10g of iron was involved in this chemical reaction
We can establish that :
3moles of Fe would produced 4 moles of Hydrogen gas
Therefore:
Number of moles of iron = mass of Fe / mloar mass of iron
Mass of Fe = 10g
Molar Mass of Fe = 55.85g/mol
Therefore, number of moles of iron= 10/55.85
Number of moles of iron = 0.179mol
3moles of Fe would produced 4 moles of Hydrogen gas
So, 0.179mol of Fe would give 0.179x4/3
The number of mole of Hydrogen gas produced is 0.239mol.
Answer:
The pressure inside the container would increase with each additional pump.
Explanation:
- From the general gas law of ideal gases:
<em>PV = nRT,</em>
where, P is the pressure of the gas.
V is the volume of the gas.
n is the no. of moles of the gas.
R is the general gas constant.
T is the temperature of the gas.
- As clear from the gas law; the pressure of the gas is directly proportional to the no. of moles of the gas.
<em>P α n.</em>
- As gas particles are pumped into a rigid steel container, the no. of moles of the gas will increase.
So, the pressure of the gas will increase.
<em>Thus, the right choice is: The pressure inside the container would increase with each additional pump.</em>
Answer:
liquid oxygen is highly flammable
Explanation:
near any source of heat. liquid oxygen can explode to flames thus being hazardous
I think the answer is c since the it’s looking at NW, the wind is coming from SE
