Only coniferous trees have thin, waxy, needle-like leaves that drop throughout the year and help to retain water.

<h3>What are coniferous trees?</h3>

Coniferous trees are evergreen trees that produce cones.

In addition, they produce waxy and needle-like leaves that help them conserve water by limiting the evapotranspiration rate as a result of reduced surface area.

Examples of conifers include pine trees and spruces.

Where is the mass of an atom found
Virty [35]

Answer:

The mass of an atom is found in its nucleus.

Explanation:

An atom is made of three different particles: protons, neutrons and electrons.

Protons (positive charge) and neutrons (no charge) each have a mass of 1 AMU. They are both found in the nucleus (centre) of the atom.

Electrons (negative charge) are considered to have a mass of 0. Their mass is not actually 0, but very close so we do not count them. They are not in the nucleus, but found in shells surrounding the atom.

To calculate the mass of an atom, we add the number of protons and the number of electrons.

If an ideal gas has a pressure of 2.97 atm, a temperature of 449 K, and has a volume of 58.35 L, how many miles of gas are in th
soldi70 [24.7K]
N = ?

T = 449 K

V = 58.35 L

P =2.97

R = 0.082

Use the clapeyron equation:

P x V = n x R x T

2.97 x 58.35 = n x 0.082 x 449

173.2995 = n x 36.818

n = 173.2995 / 36.818

n = 4.70 moles

hope this helps!
