Answer:

I believe your answer is C.

Explanation:

First of all, if you pay attention to the details of the question it states that scientific hypothesis should be specific and demonstrate the relationship between the independent and dependant variable.

Answer A - Does demonstrate the relationship between the independent and dependant variable. but it's not very specific. Thus it is Not the answer.

Answer B - is not specific or demonstrates the relationship between the independent and dependant variable. Thus it is Not the right answer.

Answer C - Fits the criteria as it is specific, and demonstrates the relationship between the independent and dependant variable. Thus it is the Right answer

Answer D - is in the same category as B so again is Not the right answer.

Therefore your only option is C. Your welcome, and have a wonderful day

.25 g of each of the following gasses are taken at 27°C and 600 mm
horsena [70]

HI has the least volume

<h3>Further explanation</h3>

Given

Gasses and molar mass

Required

The least volume

Solution

Ideal gas law

PV=nRT

V = (nRT)/P

n = mass : MW(Molar weight=molar mass)

\tt V=\dfrac{\dfrac{mass}{MW}RT }{P}\\\\V=\dfrac{mass.RT}{MW.P}

<em>so V is inversely proportional to MW(molar mass)</em>

Because the values of P, R, T, and mass are the same, what matters is the value of the molar mass of each compound. The larger the molar mass the smaller the volume

From the available molar mass data, HI has the largest molar mass, so HI has the smallest volume

Which grouping has the least complex body plan? If you were on a research expedition in the kingdom of Tonga, a coral atoll in t
Kryger [21]
YES, I WOULD FIND THOSE ORGANISMS.

<span>The Kingdom of Tonga is a Polynesian Archipelago in Oceania consisting of 176 islands. During a month long coral reef research mission in Tonga, the Foundation focused on islands in the Ha’aipi group, Vava’u and Niuatoputapu. Haʻapai, directly west of the Tonga trench in the central part of Tonga, is made up of 51 volcanic islands and includes Kao, the highest point in the kingdom (1,046 m). Vavaʻu has one large island and 40 smaller ones, and includes the second largest city, a large harbor.  The north side of the main island is lined by 200 m high cliffs and extensive open network of fjord-like channels that stretch inland on the north side. Nearly 300 km north of Vavaʻu, close to the border of Samoa is Niuatoputapu, a sparsely inhabited (population 150)  eroded remnant of a volcano surrounded by a large uplifted reef. This island was badly damaged by a tsunami following a submarine earthquake off Samoa in 2009.</span>

If 1,000 mL = 1 L, which of the following are possible conversion factors for liters and milliliters? Check all that apply.
Fudgin [204]

Answer:

Two conversion factors:

         1=\dfrac{1L}{1,000ml}\\ \\ \\ 1=\dfrac{1,000mL}{1L}

Explanation:

You can create two possible <em>conversion factors</em>, one to convert from mL to L, and one to convert from L to mL

<u />

<u>a) From mL to L</u>

To convert mL to L you need to multiply by a conversion factor that has mL on the denominator and L in the numerator.

Your starting point is: 1,000mL=1L

Then, divide both sides by 1,000mL (this will be on the denominator of the fraction);

       1,000mL=1L\\\\ \\\dfrac{1,000ml}{1,000mL}=\dfrac{1L}{1,000mL}\\ \\ \\ 1=\dfrac{1L}{1,000mL}

<u>b) From L to mL</u>

Divide both sides by 1 L:

            1,000mL=1L\\\\ \\\dfrac{1,000ml}{1L}=\dfrac{1L}{1L}\\ \\ \\ 1=\dfrac{1,000mL}{1L}
