Answer:
Word that comes from a Greek word
Explanation:
Glucose is a natural monosaccharide, which has the following molecular formula: C6H12O6
From the chemical point of view, this molecule is a hexose (this is, it has 6 carbon atoms) and an aldose (since it has an aldehyde group)
Glucose as a word has its origin from the Greek word “gleukos”, which means “sweet wine”, and the suffix “ose”, which is used to for a sugar
French people then adapted this word (in order to define a new chemical word, to differentiate the type of sugar found in grapes, slight different from sugar found in other elements such as honey)
c. table salt is a metalloid with properties of both reactants
Answer:
74
Explanation: Mass number = protons + neutrons
Mass number = 33 + 41
Mass number = 74
The mass number of this atom is 74
Answer : The correct option is,
Explanation :
Molar mass : It is defined as the mass of the substance in grams or kilograms present in the one mole of substance.
The unit of molar mass is, gram/mole or g/mol.
Given : Molar mass of = 44.01 g/mole
That means, one mole of contains 44.01 gram of .
Based on the chemical equation, to balance the given equation we should use 2 as a coefficients of HCl on reacatnt side of the reaction.
<h3>What is balanced equation?</h3>
Balanced chemical equations are those equation in which each entities are present in same amount on reactant side as well as on the product side of the chemical reaction.
Given chemical reaction is:
Zn + HCl → ZnCl₂ + H₂
In the above reaction equation is not balanced as number of chlorine and hydrogen atoms are not equal on both sides, so balanced equation will be:
Zn + 2HCl → ZnCl₂ + H₂
Hence we add 2 as a coefficient of HCl to balance the equation.
