Answer:
8.38×10raise to power 23
Explanation:
mass of sugar=density ×volume
=. 1.59g/ml×25ml=39.75
no. of miles= given mass/ molar mass
= 39.75/342.3g / mole
1 mole of sugar =C12 H22 O11
contains
12× 6.023 × 10 ∆23=72.28× 10∆ 23 ×6.023×10²³
= 8.38× 10²³
Answer:
In a chemical reaction, one or more substances called reactants are combined or broken down to form products.
Explanation:
Chemical reaction:
In a chemical reaction one or more substance converted into the another substance.
The substances that reacts or combine during the chemical reaction are called reactants while the new species formed as a result of chemical reaction are products.
There are different types of reaction given below:
Decomposition reaction:
It is the reaction in which one reactant is break down into two or more product.
AB → A + B
Synthesis reaction:
It is the reaction in which two or more simple substance react to give one or more complex product.
Single replacement:
It is the reaction in which one elements replace the other element in compound.
AB + C → AC + B
Double replacement:
It is the reaction in which two compound exchange their ions and form new compounds.
AB + CD → AC +BD
Answer:
F < O < Cl
Explanation:
Fluorine has a greater effective nuclear charge than oxygen does, meaning that the electrons are drawn tighter and closer toward the nucleus. Fluorine has 9 protons and 9 electrons while oxygen only has 8 protons and electrons. Chlorine has a larger atomic radius than both fluorine and chlorine because has another energy level (shell). Although chlorine has the same effective nuclear charge as fluorine, chlorine has more electrons, 17, which requires an additional shell to contain them.
