Determining the Limiting Reagent

One reactant (A) is chosen, and the balanced chemical equation is used to determine the amount of the other reactant (B) necessary to react with A. If the amount of B actually present exceeds the amount required, then B is in excess, and A is the limiting reagent.

Answer:

10°C

Explanation:

Here the problem deals with the relationship between the amount of heat lost and the temperature change of a body.

From the relationship below:

        H  = m C Δt

H is the quantity of heat

m is the mass

C is the specific heat

Δt is the change in heat

  We can see that the quantity of heat is directly proportional to the Δt, so as more heat changes occur, so also is the value of Δt .

Explanation:

The mass of an object is the product of its volume and density. The mass of a the object with a volume of 825 cm³ and a density of 13.6 g/cm³ is 11220 g.

Density of substance is the measure of its mass per unit volume. It describes how closely its particles are packed. Density depends on the bond type, temperature and pressure.

Volume of the object is the space occupied by its particles. Volume can be expressed in L, ml, cm³, dm³ etc. Only solids and liquids has a definite volume and the volume of gases is that of the container.

Give that, volume of the object = 825  cm³

density =  13.6 g/cm³

Mass = volume × density

m = 825  cm³ ×  13.6 g/cm³ = 11220 g

Therefore, the mass of the object is 11220 g.

Answer:

The most apparent general environmental factor affecting the distribution of a species is climate. Suitable conditions of temperature and moisture are vital to all organisms. Certain species are intolerant of cold; other species cannot live in warm climates.

Answer:

False

Explanation:

Metamorphic rocks form when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors.

This question is reffering to sedimentary rocks, so it's false.

Answer:

Weathering (breaking down rock) and erosion (transporting rock material) at or near the earth's surface breaks down rocks into small and smaller pieces. When the molten rock cools it forms an igneous rock. Metamorphic rocks can form from either sedimentary or igneous rocks.

Answer:

A. a ball dropped from the top of a building increases in speed until it hits the ground.

A ball dropped from the top of a building in speed until it hits ground is the situations violates the law of conservation of energy. Therefore, option A is correct.

According to the law of conservation of energy, energy is neither created nor destroyed. When you roll a toy car down a ramp, and it collides with a wall, the energy is transferred from kinetic to potential.

Energy conservation does not imply energy savings. Instead, energy is neither created nor destroyed, according to the law of conservation of energy. When people use energy, it does not vanish. Energy is transformed from one form of energy to another.

The law of conservation of energy is violated when a ball is dropped from the top of a building at high speed until it hits the ground.

Thus, option A is correct.

Answer:

Explanation:

Ideal gas law is valid only for ideal gas not for vanderwaal gas. Therefore, the correct option is option B that is 131.5l. There is no force of attraction between the particles.

Ideal gas equation is the mathematical expression that relates pressure volume and temperature. Ideal gas is a hypothetical gas. Vanderwaal behave as ideal gas at high temperature and low pressure.

Mathematically,

PV=nRT

where,

P = pressure=1 atm

V= volume=?

n =number of moles=given mass/ molar mass

                                =  492.2/ 83.79

                                = 5.87 moles

T =temperature = 273K

R = Gas constant = 0.0821 L.atm/K.mol

1× V = 5.87 × 0.0821 L.atm/K.mol × 273 K

V =131.5l

131.5l is the  volume of a 492.2g sample of Kr gas.

Therefore, the correct option is option B that is 131.5l.

Answer:

Molarity = 2.4 M

Explanation:

Given data:

Mass of silver fluoride = 12.7 g

Volume of water = 125 mL (125 mL× 1 L /1000 mL = 0.125 L)

Molarity of solution = ?

Solution:

Number of moles of silver fluoride:

Number of moles = mass/molar mass

Number of moles = 12.7 g/ 41.98 g/mol

Number of moles = 0.30 mol

Molarity:

Molarity = number of moles of solute / volume in L

Molarity = 0.30 mol / 0.125 L

Molarity = 2.4 M
