Answer:
Yes, it is still sugar.
Explanation:
Melting is a physical change, in which a substance passes from a state of aggregation to other. During physical changes, the nature or identity of the subtance does not change. So, when sugar melts it changes only its state of aggregation: it passes from the solid state to the liquid state, but it is still the same substance: sugar.
Answer: 0.8 M
Explanation:
molarity = (moles of solute)/(liters of solution) = 1.25/1.5 = 0.8 M
Answer:
The C4+ ion has the smallest ionic radius
Explanation:
In the periodic table, the size of an atom increases on going downwards in a group.
On the other hand, in a period, size decreases on going from left to right
The size of cation is smaller than its parent atom.
Lithium-ion (Li+) is the most left so it has the biggest radius.
More to the right ( this means a smaller ionic radius) , we have Berylium-ion (Be2+).
More to the right, so smaller than Be2+, we have B3+
The ion the most to the right, we have C4+
The C4+ ion has the smallest ionic radius
Li+ > Be2+ > Be3+ > C4+
Answer is "C"
alpha decay is an emission of ₂⁴He nucleus. If an element undergoes an alpha decay, the mass of the daughter nucleus formed is reduced by 4 compared to mass of parent atom and atomic number is reduced by 2 compared to atomic number of parent atom.
