The volume of the red mineral piece in millilitres is 10 millilitres.

Volume in chemistry is a measure of the amount of space that matter occupies.

Matter is defined as a physical substance that occupies space and has a mass. In physical sciences like chemistry, the standard unit of volume is cubic metres (m³). From this unit, other units are derived including litre (L) and millilitre (mL).

According to this question, a graduated cylinder is filled to 25.0 mL with water and a piece of a red mineral is placed in the cylinder, displacing the level to 35.0 mL.

This suggests that the volume of the red mineral placed in the cylinder can be calculated as follows:

Volume of red mineral = 35.0mL - 25.0mL = 10.0mL

Therefore, 10mL is the volume of the piece of red mineral.

In the case of phosphorus, 5 covalent bonds are possible - as in PCl5.

A covalent bond is formed when two atoms exchange one or more pairs of electrons. The two atomic nuclei are concurrently drawing these electrons to them. When the difference between the electronegativities of two atoms is too tiny for an electron transfer to take place to create ions, a covalent bond is formed. Bonding electrons are collectively referred to as the electrons that are present between the two nuclei. The "glue" that holds the atoms in molecular units together is the bound pair. The simplest material with a covalent link is the hydrogen molecule.

Nutritionists express energy in calories, which are in fact 1000 real calories. one real calorie is equivalent to 4.18 joules, the universal energy unit. thus, one nutrition calorie is equivalent to 4.18 kilojoules.

Joule is the fundamental energy unit of the metric system, or the International System of Units in a later, more thorough version (SI). In the end, the meter, kilogram, and second are used to characterize it.

Calorie (cal) (cal): In the past, the definition of a calorie included the heating of water. Consequently, according to a conventional definition, one calorie is the quantity of heat needed to raise the temperature of one gram of water by one degree Celsius, from 14.5 to 15.5 degrees.

The "calorie" measured for other temperature ranges differs slightly from this, which is frequently referred to as the 15 °C calorie. The calorie has more recently been defined in terms of the joule; historically, the calorie and joule have been equivalent to mechanical heat.

The common velocity of the car and the truck after the collision is 12 m/s

From conservation of linear momentum, we understood that momentum before collision is equal to momentum after collision ie

Momentum before = Momentum after

m₁u₁ + m₂u₂ = v(m₁ + m₂)

Where

Using the above formula, we can obtain the common velocity of the car and truck. This is shown below:

m₁u₁ + m₂u₂ = v(m₁ + m₂)

Divide both sides by (m₁ + m₂)

v = [m₁u₁ + m₂u₂] / (m₁ + m₂)

v = [(1200 × 12) + (2500 × 12)] / (1200 + 2500)

v = [14400 + 30000] / 3700

Option (a) is correct. If a reaction is at equilibrium and we will increase the volume of the reaction then the Reaction will shift to the right in the direction of product.

The Reaction is,

2H2S(g) + 3O2(g) ----> 2H2O(g) + 2SO2(g) a)

According to Le Chatelier's principle, if a dynamic equilibrium is disturbed by changing the conditions the position of equilibrium shifts to counteract the change to reestablish an equilibrium. If a chemical reaction is at equilibrium and experiences a change in pressure, temperature or concentration of products or reactants, the equilibrium shifts in the opposite direction to offset the change. A change in one of the variables that describe a system at equilibrium produces a shift in the position of the equilibrium that counteracts the effect of this change.

We are increasing pressure here. Reaction will try to decrease the pressure. Hence it will move in a direction which have lesser gaseous molecules. Here product has less gaseous molecule. So equilibrium will move to right. Equilibrium moves to product side.
