Well, there’s some pretty poor choices out there, but I think chlorine trifluoride would be the worst since it would burn everything it touched.
Answer:
C: Carbon monoxide - Acidic nature
Explanation:
A) Beryllium is not soluble in water but yet it reacts with an acid and a base. Therefore, since it exhibits both basic and acidic nature, we say it is Amphoteric in nature. Thus it is correct
B)potassium super oxide has the formula KO2. It reacts with acid to form salt called potassium chloride. Thus, it is basic in nature.
C) Carbon monoxide does not react with acids or bases. Thus, it doesn't show either an acidic or basic property and we say it is a neutral oxide. This option is incorrect
D) Bismuth oxide is a basic oxide because it displays properties of a base. This options is correct
Answer:
160N
Explanation:
F = m × a
Where;
F = force (Newton)
m = mass (kg)
a = acceleration (m/s²)
According to this question, a 50kg car is pulling a 30kg car. This means that the total mass of the cars is 50kg + 30kg = 80kg
Hence, the force required to accelerate the cars at 2m/s² can be calculated this:
F = 80 × 2
F = 160kgm/s²
F = 160N
