Invertebrates affect the oxygen levels of compost and soil by reducing it.

Cellular respiration is the process by which living organisms obtain energy by breaking down food molecules in their cells.

Every living organism undergoes the process of cellular respiration and make use of oxygen molecules in the process.

This means that invertebrates will make use of the oxygen gas present in compost and the soil for respiration, hereby reducing it.

Answer:

Stone does not have organic matter in it to burn in presence of air. Hence, it is a non combustible.

Rocks are quite bundled up together. Hence, they are very difficult to get mixed together.

Answer:

because stone is not have any holes to in the heat inside the stone and the water is dont have oxygen thats why the fire is not allowed to water

you need the heat oxygen and fuel to made a fire

Answer:

The earth-atmosphere energy balance is achieved as the energy received from the Sun balances the energy lost by the Earth back into space. In this way, the Earth maintains a stable average temperature and therefore a stable climate. ... Shortwave radiation reflected back to space by clouds.

Answer:Greenhouse effect

Explanation:

The greenhouse effect causes the atmosphere to retain heat

When sunlight reaches Earth's surface, it can either be reflected back into space or absorbed by Earth. Once absorbed, the planet releases some of the energy back into the atmosphere as heat (also called infrared radiation).

Answer:

The properties of metals as well as non metals is called metalloids.

Answer:

Mass of metal = 64 g

Explanation:

Given data:

Density of metal = 4 g/mL

Volume of water = 400 mL

Volume of water + metal = 416 mL

Mass of metal  = ?

Solution:

First of all we will calculate the volume of metal

Volume of metal = (Volume of water + metal) - volume of water

Volume of metal = 416 mL -  400 mL

Volume of metal = 16 mL

Mass of metal:

d = m/v

4 g/mL = m/  16 mL

m = 4 g/mL ×16 mL

m = 64 g

Answer:

2 moles of NO₂ contain 12.044 × 10²³ molecules  of NO₂

Explanation:

Given data:

Number of moles of NO₂ = 2.00 mol

Number of molecules of NO₂ = ?

Solution:

It will be solve through Avogadro number.

It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.  The number 6.022 × 10²³ is called Avogadro number.

1 mole = 6.022 × 10²³ molecules

2.00 mole NO₂  × 6.022 × 10²³ molecules  of NO₂  / 1 mol of NO₂

12.044 × 10²³ molecules  of NO₂

Thus, 2 moles of NO₂  contain 12.044 × 10²³ molecules  of NO₂ .

Answer:

A.  Cl₂

B.  51.36 g K

C.  245.3 g KCl

Explanation:

Balance the given chemical equation

K  +  Cl₂  ⇒  KCl

2 K  +  Cl₂  ⇒  2 KCl

A. To find the limiting reagent, first convert the mass of each reactant to moles.  The molar masses are 39.10 g/mol for K and 70.91 g/mol for Cl₂.

(180 g)/(39.10 g/mol) = 4.60 mol K

(120 g)/(70.91 g/mol) = 1.69 mol Cl₂

Now, convert moles of each reactant to moles of the product.  You can do this by using the mole ratio in the balanced chemical reaction.  The reactant with the smallest moles of product is the limiting reagent.

(4.60 mol K) × (2 mol KCl/2 mol K) = 4.60 mol KCl

(1.69 mol Cl₂) × (2 mol KCl/1 mol Cl₂) = 3.29 mol KCl

Cl₂ is the limiting reagent.

B.  You need to find out how much excess K you will have.  Since Cl₂ is the limiting reagent, you will only make 3.29 mol of KCl.  Convert this value to moles of K using the mole ratio.

(3.29 mol KCl) × (2 mol K/2 mol KCl) = 3.29 mol K

Now convert moles of K to grams.  The molar mass is 39.10 g/mol.

(3.29 mol K) × (39.10 g/mol) = 128.64 g K

This is how much K will be consumed in the reaction.  Subtract the total amount of K by the amount that will be consumed.

180 - 128.64 = 51.36 g

There will be 51.36 g of excess K.

C.  You know that you will produce 3.29 mol of KCl based on previous calculations.  Convert this to grams.  The molar mass is 74.55 g/mol.

(3.29 mol) × (74.55 g/mol) = 245.3 g KCl

You will produce 245.3 g of KCl.
