Answer: Option (D) 30N
Detailed Solution:
According to Newton's second law:
F = ma --- (A)
Given:
mass = 5kg
acceleration = 6 m/s^2
F = ?
Plug all the value in equation (A)
F = (5)(6)
Ans: F = 30N
Answer:
90 neutrons
Explanation:
#neutrons = Atomic Mass - Atomic Number
= 170 - 80 = 90 neutrons
Answer: 16 g of reacted with the magnesium
Explanation:
from the equation of reaction: 2Mg + →
48g of Mg requires 32g of O2 to yield 80g of MgO
That is :
48 : 32 : 80
Hence 12 : x: 32
xg of O2 =
= 16 g of
Therefore:
16 g of reacted with the magnesium
C3H8ONaCl is the chemical equation for this
