How do submarine volcanoes affect autotrophic bacteria?

1 answer:

5 0

Answer:A large number of autotrophic bacteria—bacteria that produce their own food—live near hydrothermal vents and submarine volcanoes.

These bacteria are considered chemosynthetic, meaning they produce food from chemical reactions usually involving carbon dioxide, oxygen, or hydrogen

Aleonysh [2.5K]

Answer:

CuSO4 cell will have the greatest amount of deposit among all three. The deposit will occur at the cathode

Explanation:

The valence of the elements in this case is as follows -

Cu - 2e-

Sn - 4e-

Cr - 3e-

CuSO4 cell will have the greatest amount of deposit among all three

The atoms of copper metal will deposit at the cathode. At the cathode, the least number of moles of electrons needed .

Hence, more amount of copper can be extracted out by the electrolyte

A rock has a density of 3.75g/cm3 and a mass of 26g. What is the volume of the rock?

Lemur [1.5K]

Answer:

<h3>The answer is 6.93 cm³</h3>

Explanation:

The volume of a substance when given the density and mass can be found by using the formula

$volume = \frac{mass}{density} \\$

From the question we have

$volume = \frac{26}{3.75} \\ = 6.93333333...$

We have the final answer as

Hope this helps you

Answer:

$y = 5cos(\frac{2\pi }{6} x)$

Explanation:

You can put that equation into a program like desmos on your browser and take a screenshot or use windows snippet tool.

Equation of a Wave: y = Acos(((2*pi)/B)x)

$y = Acos(\frac{2\pi }{B} x)$

A = Amplitude

The specific rotation of (S)-2-butanol is +13.5. If 0.119 g of its enantiomer is dissolved in 10.0 mL of ethanol and

larisa86 [58]

Answer:

+15.8°

Explanation:

The formula for the observed rotation (α) of an optically active sample is

α = [α]<em>lc </em>

where

<em>l</em> = the cell path length in decimetres

<em>c</em> = the concentration in units of g/100 mL

[α] = the specific rotation in degrees

1. Convert the concentration to units of g/100 mL

$c = \frac{\text{0.119 g}}{\text{10.0 mL}} \times \frac{10 }{10 } =\frac{\text{1.19 g}}{\text{100 mL}}$

2. Calculate the observed rotation

$\alpha = (+13.3 ^{\circ}) \times 1.19 \times 1 = +15.8^{\circ}$
