Hello,
An answer is the group of reactive nonmetals and Noble gases.
I am not sure what the colored boxes mean, referring to my periodic table. However, the nonmetals are Hydrogen, Carbon, Nitrogen, etc., including the Noble gases.
Green and purple below, then hydrogen of course.
Hmm...since soap is alkaline and tomato juice is acidic (the internet says the pH is 4.smth so yea) so the mixture would be neutral. Thus, the litmus paper would be purple
Answer:
1. 25 moles water.
2. 41.2 grams of sodium hydroxide.
3. 0.25 grams of sugar.
4. 340.6 grams of ammonia.
5. 4.5x10²³ molecules of sulfur dioxide.
Explanation:
Hello!
In this case, since the mole-mass-particles relationships are studied by considering the Avogadro's number for the formula units and the molar mass for the mass of one mole of substance, we proceed as shown below:
1. Here, we use the Avogadro's number to obtain the moles in the given molecules of water:
2. Here, since the molar mass of NaOH is 40.00 g/mol, we obtain:
3. Here, since the molar mass of C6H12O6 is 180.15 g/mol:
4. Here, since the molar mass of ammonia is 17.03 g/mol:
5. Here, since the molar mass of SO2 is 64.06 g/mol:
Best regards!
Given what we know, we can confirm that the interest rate necessary to reach $5500 in 7 years with a starting investment of $4000 on a yearly compounded interest, would be 4.7%.
<h3>Why is this the required interest rate?</h3>
Since the question did not specify any extra data to be taken into account, such as:
- Interest variance
- Monthly or yearly contributions
- Inflation rates
and so on, we can assume that all of these values are null. Therefore, if we take $4000 and add 4.7%, and repeat that every time using our new totals, after 7 repetitions we are left with close to $5500, which is our goal.
Therefore, we can confirm that the interest rate necessary to reach $5500 in 7 years with a starting investment of $4000 on a yearly compounded interest, would be 4.7%.
