Anyone know how to answer this?

Chemistry
1 answer:
Neporo4naja [7]3 years ago
4 0

Answer:

i metal

ii nonmetal

iii metal

iv nonmetal

Explanation:

If you look up what the element of a heater is, you get a picture of some sort of rod. It's the heating element of the heater, and must be some type of metal to conduct electricity and warm up. Fishing rods are made of either fiberglass, graphite, or carbon fibre. These are nonmetals. In order for a lightning rod to conduct electricity and bring the lightning down to the ground, it has to be metal. You wouldn't want a metal oven mitt, as that would burn your hand.

Interpret the following equation for a chemical reaction using the coefficients given: H2(g) + Cl2(g) 2 HCl(g) On the particulat
jeyben [28]

Answer:

On the particulate level: 1 molecule of H₂(g) reacts with 1 molecule of Cl₂(g) to form 2 molecules of HCl(g).

On the molar level: 1 mole of H₂(g) reacts with 1 mole of Cl₂(g) to form 2 moles of HCl(g).

Explanation:

Let's consider the following equation.

H₂(g) + Cl₂(g) → 2 HCl(g)

We can use the balanced equation to interpret the changes in two levels: the particulate level and the molar level.

On the particulate level, we consider discrete molecules.

On the particulate level: 1 molecule of H₂(g) reacts with 1 molecule of Cl₂(g) to form 2 molecules of HCl(g).

On the molar level, we think in terms of moles, considering 1 mole of particles = 6.02 × 10²³ particles.

On the molar level: 1 mole of H₂(g) reacts with 1 mole of Cl₂(g) to form 2 moles of HCl(g).

How many atoms of oxygen are in 4.00 moles of N2O5
SVETLANKA909090 [29]

Answer:

there are 20 oxygen atoms in 4.00 moles of Dinitrogen pentoxide

Explanation:

there are 2 atoms in an oxygen molecule , so each oxygen molecules has at least 2. Dinitrogen pentoxide is N2O5, which has 7 atoms, 2 nitrogen and 5 oxygen. 1 molecule of N2O5 has 5 oxygen atoms, so 4 of then would be 20

timurjin [86]

Answer:

A. boiling point

Explanation:

The correct answer is;

A. boiling point

The boiling point of a liquid is the temperature at which the vapour pressure is equal to the atmospheric pressure.

B. melting point

This option is wrong because the melting point is the temperature at which a solid undergoes a phase change to a liquid.

C. freezing point

This option is wrong because the freezing point is the temperature at which a liquid undergoes a phase change to a solid.

Which best describes the role of a primary consumer in a food web? (3 points)
RideAnS [48]
I believe the answer is B, as they only solely survive on tough and fibrous plant matter. Plants are producers because they can produce their own food instead of consuming something else to survive.
