The magnification of Robert's drawing of a wood louse can be obtained by dividing the size of the drawing (5mm) by the actual size of the wood louse (0.4mm). This gives a magnification of 12.5 times.
The magnification of a drawing can be calculated using the method 'Image size/Actual size'. In this question, Robert's drawing is of a size 5mm while the actual size of the wood louse is 0.4mm. Substituting these values into the formula, you would get 5mm/0.4mm which equates to a magnification of 12.5 times.
The magnification of Robert's drawing of a wood louse can be calculated by dividing the size of the drawing by the actual size, resulting in a magnification of 12.5.

Answer:
Magnification is the number of times larger an image is compared with the real size of the object.
Magnification = Image / Actual = 5/0.4 =12.5
Explanation:
Moles are the amount of substance
the break down of CCl₄ is as follows
CCl₄ --> C + 4 Cl
in the compound CCl₄ - 1 mol of CCl₄ contains 4 mol of Cl
so for every 1 mol of CCl₄ there are 4 mol of Cl
then in 8 mol of CCl₄ - there are 4 x 8 = 32 mol of Cl
so 8 mol of CCl₄ contains 32 mol of Cl
answer is 32 mol of Cl
of chlorine are present in 8 moles of
.
Further Explanation:
Mole is a measure of the amount of substance. It is defined as the mass of a substance that has the same number of fundamental units as there are atoms in 12 g of carbon-12. Such fundamental units can be atoms, molecules or formula units.
In , both carbon and chlorine are non-metals. Carbon has four valence electrons whereas chlorine has seven valence electrons. Both share two electrons with each other and a single covalent bond is formed between a carbon and a chlorine atom. So carbon forms four single bonds with four chlorine atoms in order to complete its octet and the octet of chlorine is also fulfilled. This bond is formed due to sharing of the electrons and therefore
is a covalent compound. (Refer to the attached image)
is a covalent compound. So 1 mole of
contains 1 mole of carbon and 4 moles of Cl.
Number of moles of Cl in 1 mole of = 4
So the number of moles of Cl in 8 moles of is calculated as follows:
So 8 moles of contain 32 moles of Cl.

The theoretical yield of carbon dioxide can be calculated using the stoichiometric ratio in the balanced equation for the reaction. It is the amount of product that would be obtained if all reactants were completely converted to product under ideal conditions. The theoretical yield can be calculated by multiplying the amount of the starting reactant by the stoichiometric ratio in the balanced equation.
Theoretical yield is the amount of product that would be obtained from a chemical reaction if the reaction proceeded perfectly and all reactants were completely converted to product. In this case, the balanced equation shows that 1 mole of H3C6H5O7 reacts with 3 moles of NaHCO3 to produce 3 moles of CO2. Therefore, the theoretical yield of carbon dioxide would be 3 times the amount of H3C6H5O7 given.
Example: If 2 moles of H3C6H5O7 are given, the theoretical yield of CO2 would be 3 x 2 = 6 moles.
Note that the theoretical yield assumes ideal conditions and perfect conversion, so the actual yield may be less due to factors like incomplete reactions or side reactions.

Answer:
C6H12O6 + 6O2 -> 6CO2 + 6H2O + 38ATP
Explanation:
glucose + oxygen gas -> carbon dioxide + water + ATP
Answer:
C 6 H 12 O 6 + 6 O 2 --> 6 CO 2 + 6 H 2 O + ATP is the complete balanced chemical formula for cellular respiration.
B. positively charged.
C. negatively charged.
D. not part of an electrolyte.
Answer:
The correct answer is option B. positively charged.
Explanation:
A positively charged ion is an atom that readily loses its one or more electrons in a compound. Positively charged ion generally has same number of electrons and protons which means they are neutral charge atom. These atoms are generally attracted to negatively charged ion that lack electron in outer shell.
Thus, the correct answer is option. B. positively charged.
