Answer:

The protons and electrons of an atom are attracted to each other. They both carry an electrical charge. Protons have a positive charge (+) and electrons have a negative charge (-). The positive charge of the protons is equal to the negative charge of the electrons.

Imagine that you have a 6.50 L gas tank and a 4.50 L gas tank. You need to fill one tank with oxygen and the other with acetylen

Burka [1]

Answer:

We have to fill the acetylene tank with a pressure of 60.67 atm to ensure that you run out of each gas at the same time

Explanation:

Step 1: Data given

Volume of tank 1 = 6.50 L = oxygen

Volume of tank 2 = 4.50 L = acetylene

Pressure in the oxygen tank = 105 atm

Step 2: The balanced equation

2 C2H2 + 5 O2 → 4 CO2 + 2 H2O

For 2 mol C2H2 we need 5 moles O2 to produce 4 moles CO2 and 2 moles H2O

Step 3: Calculate the pressure of the acetylene tank

For 2 mol C2H2 we need 5 moles O2 to produce 4 moles CO2 and 2 moles H2O

This means for each 5 moles O2 we have 2 moles acetylene

Pressure (105 atm) * (2/5) * (6.50 / 4.50) = 60.67 atm

We have to fill the acetylene tank with a pressure of 60.67 atm to ensure that you run out of each gas at the same time

show transcribed data consider two organic molecules, ethanol and benzene. one dissolves in water and the other does not. why? t

aalyn [17]

Benzene lacks a polar O-H bond, but ethanol does. Benzene C6H6 with ethanol C2H6O.

Benzene fails the iodoform test, whereas ethanol does.

While ethanol burns with a non-luminous flame, benzene produces a sooty flame.

Iodoform testing shows that ethanol passes whereas benzene does not.

In contrast to benzene, which generates a sooty flame, ethanol burns with a non-luminous flame.

Water does not mix with benzene, but organic solvents do.

It is a colorless liquid with a pleasant scent.

Benzene has a high melting point and a moderate boiling point.

It burns with a sooty flame and is quite flammable.

A clear, colorless liquid, ethanol has a distinct flavor of burning with a nice aroma. It has high flammability. Ethanol combines easily with water and a variety of organic liquids and is used to dissolve other chemical compounds.

Determine the mass in grams of 3.75 x 10^21 atoms of zinc. (the mass of one mole of zinc is 65.39 g)

Nastasia [14]

Answer: The mass in $3.75 \times 10^{21}$ atoms of zinc is 0.405 g.

Explanation:

Given: Atoms of zinc = $3.75 \times 10^{21}$

It is known that 1 mole of every substance contains $6.022 \times 10^{23}$ atoms. So, the number of moles in given number of atoms is as follows.

$Moles = \frac{3.75 \times 10^{21}}{6.022 \times 10^{23}}\\= 0.622 \times 10^{-2}\\= 0.0062 mol$

As moles is the mass of a substance divided by its molar mass. So, mass of zinc (molar mass = 65.39 g/mol) is calculated as follows.

$Moles = \frac{mass}{molar mass}\\0.0062 mol = \frac{mass}{65.39 g}\\mass = 0.405 g$

Thus, we can conclude that the mass in $3.75 \times 10^{21}$ atoms of zinc is 0.405 g.
