Behind your house, there's a gorgeous pond filled with frogs. You notice that the frogs behind Mr. Archer's house often have thr

ee legs. You start wondering if the fertilizer that Mr. Archer uses for his lawn is causing the deformities in the frogs. You collect 10 frogs and put the special fertilizer in their container (Group A). You put another 10 frogs and place them in a different container with just water (Group B). A week later, 7 out of 10 of the frogs in group A grew only three legs. The frogs in group B grew four legs.

aniked [119]
<span>Since at STP, the molar volume is 22.4 L, all of these containers have one mole of gas. The one with the highest atomic or molecular weight is the heaviest: : A) H2 - 2 g/mole B) N2 - 28 g/mole C) O2 - 32 g/mole D) CO2 - 44 g/mole E)He - 4 g/mole Ans will CO2 - 44 g/mole with the highest atomic or molecular weight is the heaviest.</span>

What is the measure of force per unit area.
Brut [27]

Pressure

Explanation:

Pressure is a measure of force per unit area.

Pressure is defined as the force exerted on a body across a unit area. The unit of pressure is N/m² or Pascal.

                Pressure = \frac{Force}{Area}

The more the force acting on a body the more the pressure felt. A small surface area and a large force increases pressure on a body.

it is right to say that pressure is proportional to force but inversely proportional to area.

What is the maximum mass of s8 that can be produced by combining 89.0 g of each reactant?
lidiya [134]

Answer : We can produce 125.7 g of S_{8}.


Explanation : The reaction will be

8SO_{2} + 16H_{2}S -----> 3S_{8} + 16H_{2}O


The molecular mass of SO_{2} is 64.1 g/mol

and molecular mass of H_{2}S is 34.1 g/mol


For every mole of SO_{2} we would need twice of H_{2}S moles, so for every 3 moles of S_{8} we need 16 moles of H_{2}S


Now, we can calculate number of moles S_{8}

2.61 X (3/16) = 0.49 moles


Here, the molecular mass of S_{8} is 256.8 g


multiplying it with the number of 0.49 moles we get, 256.8 X 0.49 = 125.7 g of S_{8}.


Hence, 125.7 g of S_{8} will be produced.
