Your body temperature is usually around 37 °C. When his body is 37.8°C or greater, you typically have a fever. You might feel hot, cold, or shaky. You can tell if you have a fever by testing your temperature with a thermometer.

Pressure of gas = 1.2 atm

Volume of gas = 31 L

Temperature of gas = 87°C

Number of moles = ?

The generic gas equation will be used to address the given problem.

PV = nRT

P= Pressure

V = volume

n = number of moles

R is equal to 0.0821 atm.L/mol.K for general gases.

T = temperature in kelvin

Now we will convert the temperature.

87+273 = 360 K

by putting values,

1.2 atm × 31 L = n×0.0821 atm.L/ mol.K × 360 K

37.2 atm.L = n× 29.556 atm.L/ mol

The percent ionization of a 2M solution of acetic acid at 25˚C is 0.0036%.

Acetic acid is a weak acid and it ionizes only partially in an aqueous solution, meaning not all of the acetic acid molecules will dissociate into ions. The percent ionization of a weak acid can be calculated using the formula:

[H3O+]/[HA] = Ka

Acetic acid Ka = 1.8 x [tex]10^{-5}[/tex] at 25°C

[H3O+] = Ka x [HA] = 1.8 x [tex]10^{-5}[/tex] x 2 = 0.000036

% ionization = ( [H3O+]/[HA]) x 100 = 0.0036%

The formula for an ionic compound always indicates the smallest whole number ratio of positive to negative ions within the crystal.

Ionic compounds have ionic bonds that result from the transfer of electrons between a cation (positive ion) and an anion (negative ion). In most cases, metallic and non-metallic elements make up ionic compounds. The chemical is neutral by definition but contains positively and negatively charged ions known as anions and cations.

The ratio of cations which are the positively charged ions to anions which are the negatively charged ions in an ionic compound's formula must be the smallest possible whole number.

The correct statement is for nuclear fusion reaction: A)For large nuclei, the mass of the original nucleus is greater than the mass of the products.

This statement is based on the mass-energy equivalence, which states that the mass and energy of a system are equivalent and can be converted into each other according to the famous equation E=mc². In nuclear fusion reactions, the total mass of the products is less than the total mass of the reactants. This difference in mass is converted into energy and released as radiation, in the form of heat, light and other forms of radiation. Therefore, in a nuclear fusion reaction, the binding energy of the lighter nuclei is less than the binding energy of the heavier nucleus and the mass of the original nucleus is greater than the mass of the products, that's why energy is released.

the percent error for the density of the liquid in each graduated cylinder is -1.38% in A and 1.39% in B

To calculate the percent error for the density of the liquid in each graduated cylinder, we need to use the following formula:Error percent is calculated as [(experimental value - acceptable value) / accepted value]. x 100. First, we'll calculate the density of the liquid in graduated cylinder A: Density of liquid A = mass of liquid A / volume of liquid A = (23.54 - 17.83) g / 5 mL = 3.56 g/mLNow we'll calculate the percent error for density of liquid A: % Error = [(3.56 g/mL - 3.61 g/mL) / 3.61 g/mL] x 100 = -1.38%. Next, we'll calculate the density of liquid B: Density of liquid B = mass of liquid B / volume of liquid B = (23.9 - 18.07) g / 5 mL = 3.61 g/mL. Now we'll calculate the percent error for density of liquid B:% Error = [(3.61 g/mL - 3.56 g/mL) / 3.56 g/mL] x 100 = 1.39%. It's worth noting that the percent error for the density of liquid A and B are opposite in sign and similar in magnitude, this implies that the measurement errors in mass and volume are likely to be canceled out when measuring the density, resulting in relatively low error.
