How many molecules are in 2.00 moles of h2o

Answer:

Radius of the steel ball is 4.6mm

Explanation:

Hello,

To find the radius of the steel, we'll have to calculate it from it's volume which can be gotten from the density of the material.

Data;

Mass = 3.25g

Density = 7.86g/cm³

Density = mass / volume

Volume = mass / density

Volume = 3.25 / 7.86

Volume = 0.413cm³

Volume of a steel = 4/3πr³

0.413 = 4/3 × π × r³

0.413 = 1.33 × 3.14 × r³

0.413 = 4.1762r³

r³ = 0.413 / 4.1762

r³ = 0.099

Take the cube root of both sides

r = 3√(0.099)

r = 0.46cm

From metrics table

1cm = 10mm

0.46cm = x mm

x = (0.46 × 10)

x = 4.6mm

The radius of the steel ball is 4.6mm

Answer: B They have higher reproductive rates.

Asexual reproduction is a mode of reproduction, which takes place in simple organisms. This mode of reproduction does not require the formation of gametes by the living organisms. The offsprings produced are usually larger in number as compared to those produced in the sexual mode of reproduction. The offsprings are genetically identical to the parent organisms.

Although, the life span of the asexually reproducing organisms is low, and the organisms produced are typically shorter than the sexually reproducing organisms. But, they have higher reproductive rates than sexually reproducing organisms. This because of the fact that these organisms are simple. They do not require to form or develop sex cells like sexually reproducing organisms. They just require favorable environment conditions to develop a new organism. For example, budding in yeast, the bud develops as an outgrowth on mother yest cell, which detaches in maturity and germinate to form new yeast organism.

Answer:

The forest will become very dry and things that need water will die

The statement which best describes Charles law is: A) If volume increases, temperature increases.

What is Charles law?

Charles law states that when the pressure of an ideal gas is kept constant, the volume of a gas is directly proportional to the absolute temperature of the gas.

Mathematically, Charles law is given by this formula;

This ultimately implies that, as the volume of an ideal gas increases, its temperature also increases in accordance with Charles law.

A) If volume increases, temperature increases

The law is V/T, meaning the two values are directly proportional, as one increases, the other increases too.
