Answer:
hurricanes form over warm oceans
Explanation:
because it can not form in hot nor cold oceans
Answer:
Mass of C = 47.37g
Mass of H = 10.59g
Mass of O = 42.04g
The total mass of these elements is 100g, taking a proportion of their molar masses.
C = 47.37/12= 3.95
H = 10.59/1 = 10.59
O = 42.04/16= 2.63.
Dividing through with the smallest proportion which is 2.63
C=3.95/2.63 = 1.5
H =10.59/2.63 =4
O = 2.63/2.63= 1
Multiplying through by 2 to get a whole number.
C = 1.5x2 = 3
H= 4x2 = 8
O = 1x2= 2
The empirical formula is C3H6O2
(Empirical formula)n= molecular mass
(C3H8O2)n =228.276
(12x3 +8+16x2)n= 228.276
76n = 228.276
n = 228.276/76
n = 3
Molecular formula = Empirical formula
=(C3H8O2)3 = C9H24O6
The molecular formula is C9H24O6
One of the most convenient ways of finding or calculating for the
midpoint of the line segment is to get the average of the coordinates of the
points.
Average of abscissa = (0 + 0) / 2 = 0
Average of ordinate = (0 + 15) / 2 = 7.5
Hence, the midpoint of the line segment is equal to (0, 15/2).
The value of the y-intercept is 15/2.
Answer: Option (c) is the correct answer.
Explanation:
A particle that contains two protons and two neutrons bounded together is known as an alpha particle.
It is known that an alpha particle has a large mass and due to this they travel very slowly. As a result, they tend to have low velocity.
Hence, we can conclude that alpha particles cannot penetrate deeply into solids because they have low velocity.
