A. The correctly balanced equation is that in which the number of atoms of a certain element at the left-hand side is similar to that in the right hand side or the reactant side and product side, respectively. From the given equation, the answer would be,
C. Cl2 + 2NaI --> 2NaCl + I2
B. In the given chemical reaction above, heat is emitted such that it appears in the product side of the equation. Hence, this is an example of a combustion reaction.
C. Similar with the reasoning in letter A, the answer to this item is,
B. 2H2 + O2 --> 2H2O
Answer:
TEJ as this is a thing you wont get
Answer:
d.Energy as heat transferred into an object is determined by the amount of work done on the object.
Explanation:
Answer:
The period of oscillation is 1.33 sec.
Explanation:
Given that,
Mass = 275.0 g
Suppose value of spring constant is 6.2 N/m.
We need to calculate the angular frequency
Using formula of angular frequency

Where, m = mass
k = spring constant
Put the value into the formula


We need to calculate the period of oscillation,
Using formula of time period

Put the value into the formula


Hence, The period of oscillation is 1.33 sec.
Yes, in general, metalloids are slightly reactive.
