Answer:
<u><em>DUDE YOUR ANSWER IS:</em></u>
Explanation:
<u><em>GIVEN BY YOU:</em></u>
[H+]=(1*10^-6)
Taking negitive log on both sides we get,
-㏒[H+]=-㏒(1*10^-6)
now by power rule of exponent, and also we know that
-㏒[H+]=PH so we get
PH= -(-6)(log(10))
as we know log(10)=1 hence by putting we get
PH=6
<u><em>acidic or a basic solution:</em></u>
as PH<7 hence its acidic

Answer:
a) Graph
b) Weight balance or gas syringe or upside-down measuring cylinder
Explanation:
a) Identifying a trend in temperature change over time - The best tool for this scenario is to represents the temperature daily, weekly, monthly or annually on graph to interpret the fluctuation in temperature owing to local seasonal changes and weather conditions
b) Measuring the mass of a product of a chemical reaction - If the product is solid or liquid then the balance is used to measure the mass. If the product is a gas, then gas syringe or upside-down measuring cylinder is used.
The strong base will be dissociated completely into the aqueous solution. The pOH of the solution can be determined by the concentration of the hydroxide ion. The strong bases have lower pOH value.
This one was too easy it's CCl4
