Answer:

See below

Explanation:

<u>Part a)</u>

Frequency = No. of vibrations / Time

<u>For Drum A:</u>

No. of vibrations = 450 times

Time = 10 seconds

Drum A = 450 / 10

Frequency of Drum A = 45 Hz

<u>For Drum B:</u>

No. of vibrations = 700 times

Time = 20 secs

Frequency of Drum B = 700 / 20

Frequency of Drum B = 35 Hz

<u>Part b:</u>

Since frequency is directly proportional to the pitch. Hence, the drum with higher frequency will have a higher pitch. So, Drum A produces notes with higher pitches.

\rule[225]{225}{2}

Hope this helped!

GIVING 20 POINTS!! Apply Concepts Two chemists each plan an investigation in which they will combine hydrogen gas with chlorine
Montano1993 [528]

Answer:

Yes, the investigations will reach similar conclusions about the reactivity of H2 and Cl2

Explanation:

1. The law of multiple proportions says that when elements form compounds, the proportions of the elements in those chemical compounds can be expressed in small whole number ratios.  This means that regardless of whether 1000 times more of the products are used, the reactivity of the products is established by the chemical reaction

2. The law of multiple proportions is an extension of the law of definite composition, which states that compounds will consist of defined ratios of elements.

3. A reaction with more reactants will need more care because more products are produced, which can be toxic

4. H2 and Cl2 reactivity does not depend on the quantities but the chemical properties of each compound

10g of an unknown compound are added to water to form a 7.89 molar solution. if 2 liters of solution are present, what is the mo
Citrus2011 [14]
10 / (7.89) (2) 

molarity equation is M = Moles of solute / Liters of solution

7.89 = Moles of solute / 2

(7.89)(2). The question asks for the molar mass which is defined as g/mol. Dividing would give you the unknown compound.
