Answer: Magnesium and Bromine/MgBr2 = Ionic compounds

Explanation: When atoms form together they can form between Ionic Compounds and molecules; this could depend on if they're joined by Covalent bonds as well because when atoms form with Covalent bonds, it forms Molecules.

Answer:

Gravity

Explanation:

All matter exerts a force, which is called , that pulls all other matter towards its center. The strength of the force depends on the mass of the object: the Sun has more gravity than Earth, which in turn has more gravity than an apple. Also, the force weakens with distance. Objects far from the Sun won’t be influenced by its gravity.

answer yes if the substance becomes part of the filtrate or answer no if the molecule does not become part of the filtrate

SVETLANKA909090 [29]

Yes, the substance becomes the part of filtrate. No, the molecule does not become part of the filtrate.

<h2>What is filtrate?</h2>

The most common example is making tea. While preparing tea, a filter or a sieve is used to separate tea leaves from the water. Through the sieve pores, only water will pass. The liquid which has obtained after filtration is called the filtrate; in this case, water is the filtrate.

<h3>Which substance becomes the part of the filtrate?</h3>

The substances that are normally found in the filtrate are plasma components (such as water, nutrients, dissolved gases, electrolytes, and metabolic wastes) excluding plasma proteins and blood cells.

<h3>Why molecule becomes the part of the filtrate?</h3>

Proteins are large molecules that cannot pass the wall of capillaries during filtration, hence, this molecule is not normally part of the filtrate.

If you reacted 88.9 g of ammonia with excess oxygen, what mass of nitric oxide would you expect to make? You will need to balanc

KonstantinChe [14]

1) Balanced chemical equation

4NH3(g) + 5O2(g) ---> 4NO(g) + 6H2O(g)

2) State the molar ratios

4 mol NH3 : 5 mol O2 : 4 mol NO : 6 mol H2O

3) Convert 88.9 g of ammonia to moles, using the molar mass

molar mass of NH3 = 14 g/mol + 3 * 1 g/mol = 17 g/mol

number of moles = mass in grams / molar mass = 88.9 g / 17 g/mol = 5.23 mol NH3

4) Make the proportion

4 mol NO / 4 mol NH3 = x / 5.23 mol NH3=> x = 5.23 mol NO

5) Convert 5.23 mol NO to grams

molar mass NO = 14 g/mol + 16g/mol = 30 g/mol

mass = number of moles * molar mass = 5.23 mol * 30 g/mol = 156.9 g ≈ 157 g

Answer: 157 grams

How do we use biomass as an energy source?

kherson [118]

Biomass<span> contains stored </span>energy<span>. That's because plants absorb </span>energy<span> from the sun through the process of photosynthesis. When </span>biomass<span> is burned, this stored</span>energy<span> is released as heat. Burning </span>biomass<span> releases carbon dioxide

acetone evaporates more quickly than water at room temperature. what can you say about the relative strenth of the intermolecula

hodyreva [135]

Explanation:

Volatility means the ability of a substance to readily evaporate into the atmosphere.

In water, there is hydrogen bonding which is stronger in nature. As a result, molecules of water are held tightly with each other. So, more heat is required to break these bonds.

Hence, water has higher boiling point than acetone.

Whereas in acetone, molecules are held by weak intermolecular forces. As a result, bonding between the molecules of acetone is weak. So, this bonding can be broken down by slight heating.

As a result, acetone readily evaporates into the atmosphere. Hence, acetone is more volatile than water.
