Answer is: particles.

Dalton's atomic theory:

a) All matter consists of indivisible particles called atoms.

b) Atoms of the same element are similar in shape and mass, but differ from the atoms of other elements.

c) Atoms cannot be created or destroyed.

d) The ratios of the masses of the second element which combine with a fixed mass of the first element will be ratios of small whole numbers.

e) Atoms of same element can combine in more than one ratio to form two or more compounds.

f) The atom is the smallest unit of matter that can take part in a chemical reaction.

g n the Ideal Gas Law lab, how is the temperature of the hydrogen gas determined? Select one: The pressure of the gas is determi
Charra [1.4K]

Answer:

The volume of the gas is determined, which will allow you to calculate the temperature.

Explanation:

According to Charles law; the volume of a given mass of an ideal gas is directly proportional to its temperature at constant pressure.

This implies that, when the volume of an ideal gas is measured at constant pressure, the temperature of the ideal gas can be calculated from it according to Charles law.

Hence in the Ideal Gas Law lab, the temperature of an ideal gas is measured by determining the volume of the ideal gas.

A 45 kg box is sitting on a window ledge 2.0 m above the ground. What is the potential energy of the box?
Travka [436]

Answer:

<h3>The answer is 900 J</h3>

Explanation:

The potential energy of a body can be found by using the formula

PE = mgh

where

m is the mass

h is the height

g is the acceleration due to gravity which is 10 m/s²

From the question we have

PE = 45 × 10 × 2

We have the final answer as

<h3>900 J</h3>

Hope this helps you

How would you describe the image formed by a convex mirror? a. upright and larger than object c. inverted and larger than object
Alecsey [184]
One way that I would really describe these kind of mirrors would be like first, these kind of mirrors are for sure <span>virtual, upright, smaller. And this would be only due mainly because this the kind of mirror this would be. So based from my information. So based from your options, the answer would most likely be one of the options that would practically fit this. This would be known to be "</span><span> upright and smaller than object".</span>

Do all structural formulas for each amino acid have an amino group?
mina [271]
Amino acids are the monomers that make up proteins. Each amino acid has the same fundamental structure , which consists of a central carbon atom, also known as the alpha (α) carbon, bonded to an amino group (NH2), a carboxyl group (COOH), and to a hydrogen atom.
