Calculate the number of kg in 7.66 x 10-5 Gigagrams.
bonufazy [111]

Answer:

76,6 kg

Explanation:

A kg it's equal to 1x10^3 grams

A Gigagrams it's equal to 1x10^9 grams

Knowing this, a kg it's equal to 1x10^6 gigagrams

7,66*10^{-5}[gigagram]*\frac{1*10^6 [kg]}{1 [gigagram]}= 76.6 [kg]

Calculate the molarity of a solution that contains 3.00 grams Na2SO4 in 25 mL of solution.
Naddik [55]

Answer:

M Na2SO4 sln = 0.8448 M

Explanation:

  • molarity (M) [=] mol/L

∴ mass Na2SO4 = 3.00 g

∴ volume soln = 25 mL = 0.025 L

∴ molar mass Na2SO4 = 142.04 g/mol

⇒ mol Na2SO4 = (3.00 g)*(mol/142.04 g) = 0.02112 mol

⇒ M Na2SO4 sln = (0.02112 mol/0.025 L ) = 0.8448 M

What is meant by the term neutral in relation to atoms?
Sonbull [250]

Answer:

it means positive and negative charges are  equal.

Explanation:

An atom consist of electron, protons and neutrons. Protons and neutrons are present with in nucleus while the electrons are present out side the nucleus.

All these three subatomic particles construct an atom. A neutral atom have equal number of proton and electron. In other words we can say that negative and positive charges are equal in magnitude and cancel the each other. For example if neutral atom has 6 protons than it must have 6 electrons. The sum of neutrons and protons is the mass number of an atom while the number of protons are number of electrons is the atomic number of an atom.

when a neutral atom loses a electron positive charge is created because  number of protons are positive charge becomes greater than negative charge.

X → X⁺ + e⁻

When a neutral atom accept  the electron negative charge is created because negative charge is become greater than positive charge.

X + e⁻ → X⁻

A ball has a mass of 140 g. What is the force needed to accelerate the ball at 25 m/s2? (Formula: F=ma) 3.5 N 115 N 165 N 4.5
Ksju [112]
<h3>Answer:</h3>

3.5 Newton

<h3>Explanation:</h3>

We are given;

Mass of the ball = 140 g

Acceleration = 25 m/s²

Required to find the force;

  • According to Newton's second law of motion, the resultant force on a body in motion and the rate of change in linear momentum are directly proportional.
  • That is; F \alpha \frac{Mv-Mu}{t}
  • Thus; F = ma , where F is the resultant force, m is the mass and a is the acceleration.

To get the force we substitute the value of m and a in the formula;

Therefore;

F = 0.14 kg × 25 m/s²

  = 3.5 N

Hence, the force needed to accelerate the ball is 3.5 N
