Answer:

The positive charge in carbon is =4338.11 \times 10^{4} C

Explanation:

Atomic weight: An atom consists of protons, neutrons and electrons. Atomic mass is the sum of the number of protons and neutrons. The average weight of mass is called atomic mass of that atom.

The positive charge of an atom is proton.

The atomic weight of carbon = 12.0107 g/mol

Avogadro's number = 6.023×10⁻²³ atom/ mol

Charge = 1.602×10⁻¹⁹ C

The weight of carbon = 0.9 kg = 900 gram

Number of protons in carbon = 6

The positive charge in carbon is

=No. mole× Avogadro's Number× No. proton × charge per proton

=\frac {900g}{12.0107g/mol}\times( 6.023 \times10^{23} atom/mol) \times6 \times (1.602\times10^{-19}C)

=4338.11 \times 10^{4} C

Linda has two glasses of apple juice. Glass A has 40 grams of juice at 25 °C. Glass B has 40 grams of juice at 40 °C. Which of t
IgorLugansk [536]
<h2>Answer:</h2>

In both glasses have juices of same mass. But the temperature is different due to which the kinetic energy of molecules in both glasses is different.

As kinetic energy is directly proportional to temperature.

To make the kinetic energy of the molecules equal she should:

  • Heat one glass of 25°C to 40°C.

               or

  • Cool the juice of 40°C to 25°C

Which is NOT part of the definition of matter
qaws [65]

Answer:

Everything that has mass and takes up space is matter. Every day, you find something usual that either does't have mass or else don't take up space. Those things are non-matter. Basically, any type of energy or any abstract concept is an example of something that does not have matter.

Given that a for HBrO is 2. 8×10^−9 at 25°C. What is the value of b for BrO− at 25°C?
lara [203]

If Ka for HBrO is 2. 8×10^−9 at 25°C, then the value of Kb for BrO− at 25°C is 3.5× 10^(-6).

<h3>What is base dissociation constant? </h3>

The base dissociation constant (Kb) is defined as the measurement of the ions which base can dissociate or dissolve in the aqueous solution. The greater the value of base dissociation constant greater will be its basicity an strength.

The dissociation reaction of hydrogen cyanide can be given as

HCN --- (H+) + (CN-)

Given,

The value of Ka for HCN is 2.8× 10^(-9)

The correlation between base dissociation constant and acid dissociation constant is

Kw = Ka × Kb

Kw = 10^(-14)

Substituting values of Ka and Kw,

Kb = 10^(-14) /{2.8×10^(-9) }

= 3.5× 10^(-6)

Thus, we find that if Ka for HBrO is 2. 8×10^−9 at 25°C, then the value of Kb for BrO− at 25°C is 3.5× 10^(-6).

DISCLAIMER: The above question have mistake. The correct question is given as
