Answer:
C) Carla participated in an artistic activity, while Maurice participated in a scientific activity.
Explanation:
Scientific activities involve making observations, which ultimately leads to the series of steps that aims at solving the observed problem or answering a question that arises from the problem. This is the case of Maurice who is observing and recording information about ants in order to solve a curiosity (about what they feed on).
However, on the other hand, Carla is given a pictorial representation of the ants and what they carry. It is not based on curiosity or to answer a question about the ants but rather for decoration or aesthetic purposes, which is what makes her activity artistic.
It has 1 valence electron.

Explanation:I mean they said right 150 words
Answer:
denotes the molar hydrogen ion concentration
Explanation:
This is an incomplete question, here is a complete question.
A certain first-order reaction has a rate constant of 5.50 × 10⁻³ s⁻¹. How long will it take for the reactant concentration to drop to 1/8 of its initial value?
Answer : The time taken will be, 378.1 s
Explanation :
Expression for rate law for first order kinetics is given by:
where,
k = rate constant =
t = time passed by the sample = ?
a = let initial amount of the reactant = x
a - x = amount left after decay process =
Now put all the given values in above equation, we get
Thus, the time taken will be, 378.1 s
