The correct option is this: THE NUCLEUS OF AN ATOM U-235 SPLITS, RESULTING IN TWO SMALLER FRAGMENTS AND THE RELEASE OF A LARGE AMOUNT OF ENERGY.
The process of nuclear fission involves the splitting of a nucleus of a radioactive element into two smaller nuclei of different elements accompany with a large release of energy. The energy released during nuclear fission is usually used to generate electricity power. <span />
Gallium trichloride is the name of GaCI3.
Explanation:
The compound having chemical formula GaCl3 is Gallium trichloride.
The rules for naming a compound according to IUPAC is:
The net charge should always be zero in ionic compounds the prefixes are used as mono, di, tri and so on.
Metal name should come first.
Non-metal name proceed it
The anion ends with suffix 'ide'
Ga³+ + Cl- ⇔ GaCl3
In this gallium Ga is metal and Cl is non-metal with prefix 3.
In solid state the Gallium trichloride exists as a dimer which has formula as
Ga2Cl6.
It has the property of being soluble in all the solvents including alkanes.
Answer:
C-attracted.
Explanation:
When two magnets stay together they are being attracted. If they are pushing each other away, they are being repelled.
Answer:
5.61 * 10²¹ molecules
Explanation:
You have 1.25 g of malic acid, C4H.Os, an acid found in apples and other fruits. How many molecules of the acid do you have?
Solution:
A molecule is the group of two or more atoms held together by chemical bonds.
The number of molecules is calculated using the formula:
number of molecules in a substance = number of moles of substance * Avogadro constant
Avogadro constant = 6.02 * 10²³ mol⁻¹
number of moles = mass / molar mass
Given that mass = 1.25 g
molar mass of malic acid (C₄H₆O₅) = (12 * 4) + (1 * 6) + (16 * 5) = 48 + 6 + 80 = 134 g/mol
number of moles = mass / molar mass = 1.25 g / 134 g/mol = 0.0093 mol
Recall that: number of molecules in a substance = number of moles of substance * Avogadro constant
number of molecules in a substance = 0.0093 mol * 6.02 * 10²³ mol⁻¹ = 5.61 * 10²¹ molecules
Answer:
P=9
Explanation:
Formula: P = M/V
First, we need to find the volume. This can be done by: 5 x 3 x 2 which will give us 30
Now we can plug it in
P= 270/30
P=9!
