Given parameters:

Number of protons = 4

Number of neutrons = 5

Number of electrons = 4

Unknown:

Element = ?

Solution:

To determine an element, the atomic number is the most important identifier.

The atomic number is the number of protons in an atom.

Since the atom here has a proton number of 4, checking on the periodic table, it is Beryllium, Be

Write a balanced equation to show the reaction of sulfurous acid with caesium hydroxide to form water and caesium sulfite.

Soloha48 [4]

Answer:

H2SO3 + 2CsOH —> Cs2SO3 + 2H2O

Explanation:

When sulfurous acid react with caesium hydroxide, caesium sulfite and water are formed according to the equation:

H2SO3 + CsOH —> Cs2SO3 + H2O

Next, we balanced the equation by putting 2 in front of CsOH and 2 in front of H2O i.e

H2SO3 + 2CsOH —> Cs2SO3 + 2H2O

When the volume of a gas is

Montano1993 [528]

Answer:

$\boxed {\boxed {\sf 232.9 \textdegree C}}$

Explanation:

This question asks us to find the temperature change given a volume change. We will use Charles's Law, which states the volume of a gas is directly proportional to the temperature. The formula is:

$\frac {V_1}{T_1}= \frac{V_2}{T_2}$

The volume of the gas starts at 250 milliliters and the temperature is 137 °C.

$\frac{250 \ mL}{137 \textdegree C}= \frac{V_2}{T_2}$

The volume of the gas is increased to 425 milliliters, but the temperature is unknown.

$\frac{250 \ mL}{137 \textdegree C}= \frac{425 \ mL}{T_2}$

We are solving for the new temperature, so we must isolate the variable T₂. First, cross multiply. Multiply the first numerator and second denominator, then multiply the first denominator and second numerator.

$250 \ mL * T_2 = 137 \textdegree C * 425 \ mL$
