Answer:
K ^+ , CO3 ^2-
Explanation:
The compound is potassium trioxocarbonate(IV).
It contains cation (potassium ion) and acid radical ( trioxocarbonate (IV) ion).
Since K is in group 1 of the periodic table, it loses one electron to form ion i.e K^1. trioxocarbonate IV ion has a charge of 2-.and so the ions of the compound are as shown in the answer above.
Answer:
molar mass of C₃H
₈ = 44 g/mole
Explanation:
Computation of the amount of oxygen that reacts
.
⇒ 75 - 12.5
⇒ 62.5 cm³
Computation of proportion of hydrocarbons
2 mole hydrocarbons 3n+1 oxygen
⇒ 3 n + 1 = [62.5 × 2] / 12.5
⇒ 3 n + 1 = 10
⇒ n = 3
So,
Formula of the hydrocarbon is C₃H
₈
Computation of molar mass of C₃H
₈
⇒ [12×3] + [1×8]
⇒ 44 g/mole
Answer:
When energy is transformed from one from to another, energy is transferred form one form to another.
Explanation:
While the transformation of energy occur, total energy remains constant.
This is the LAW OF CONSERVATION OF ENERGY.
Answer:
A. Space Probes
A space probe is a robotic spacecraft that does not orbit Earth, but instead, explores further into outer space. A space probe may approach the Moon; travel through interplanetary space; flyby, orbit, or land on other planetary bodies; or enter interstellar space
