The equal mass indicates that both atoms have the same number of protons and neutrons.
A positive charge signifies a difference in electron count.
Assuming the atomic number is A,
the mass number equals M.
In a neutral atom, there are A electrons.
A negatively charged atom would have A + 1 electrons [while the count of protons and mass number remains unchanged].
A positively charged atom contains A - 1 electrons [with consistent protons and mass number].
For instance: Cl- and Cl+.
The density of human fat is 
. The mass of the pure fat is 11.1 lbs.
First, convert the mass from pounds to grams as follows:
1 lb=453.592 g
Thus,
Density is defined as mass per unit volume, meaning volume can be calculated as:
By substituting the values,
Consequently, the volume gained by the individual will be 
.
Answer:
This indicates that the enzyme is a type of protein.
Explanation:
It is important to remember that proteins are composed of vast numbers of amino acids. Because these amino acids are tiny units, they cannot function as a catalyst on their own.
However, when they form a polymer, the protein enzyme will possess varying shapes, sizes, and both physical and chemical attributes differing from a single monomer.
Additionally, for proteins to function actively, a specific number of amino acids must combine to create a distinct shape suited to interact with another molecule, thus accelerating the chemical reaction and functioning as an enzyme.
Explanation:
Elements provided:
F, Sr, P, Ca, O, Br, Rb, Sb, Li, S
Elements sharing similar reactivity belong to the same group in the periodic table, indicating that those in the same column exhibit comparable reactivity. Here are the identified groupings:
Li and Rb are alkali metals in group 1
Ca and Sr are alkaline earth metals in group 2
F and Br are halogens in group 7
O and S belong to group 6
P and Sb are classified in group 5 of the periodic table
Thus, these classifications illustrate elements with the same chemical characteristics.
Answer:
9.69g
Explanation:
To find the needed outcome, we first need to determine the number of moles of N2 present in 7.744L of the gas.
1 mole of gas takes up 22.4L at STP.
Thus, X moles of nitrogen gas (N2) will fill 7.744L, meaning
X moles of N2 = 7.744/22.4 = 0.346 moles
Next, we will convert 0.346 moles of N2 to grams to achieve the result sought. The calculation goes as follows:
Molar Mass of N2 = 2x14 = 28g/mol
Number of moles N2 = 0.346 moles
Find the mass of N2 =?
Mass = number of moles × molar mass
Mass of N2 = 0.346 × 28
Mass of N2 = 9.69g
Hence, 7.744L of N2 consists of 9.69g of N2
