Answer:
2
Explanation:
The compound H2CCH2 has the condensed formula C2H4. The name of the compound is ethene. The compound is unsaturated, that is, it contains multiple bonds. The compound has a formula which fits into the general molecular formulae of alkenes (olefins) which his CnH2n.
Olefins have a double bonds between the carbon atoms. That is , the two carbon atoms in Olefins are connected via a double covalent bond. This now implies that the two carbon atoms in ethene (C2H4) are connected by two covalent bonds in the lewis structure of the molecule as is common for Olefins.
To determine the mole ratio between two substances, all you need to do is look at the balanced equation for the coefficients in front of the substances you are interested in.
Answer: A
Answer:
Mass, m = 30 kg
Explanation:
We have,
Acceleration of a cart, 
Force applied, is 60 N
It is required to find the mass of the cart.
The formula of the force acting on the cart is :
m is mass of the cart
So, the mass of the cart is 30 kg.
