Answer: (2) CO
Co, Cr, and Cu are elements. Elements cannot be broken down by a chemical change, but compounds can. Since CO is a compound, it can be decomposed by a chemical change.
Answer:
The air pressure is 9.8 *10^4 pa
The water will rise to a height of 10.0 meter
Explanation:
Step 1: Data given
As a storm from moves in, you notice that a column of mercury in a barometer rises to 736 mm.
Step 2: Calculate the air pressure
The Pressure against the mercury column = h*d*g = 0.736 * 13593 * 9.81 = 9.8 * 10^4 Pa
Step 3: Calculate the height of the water
Let the Pressure the water column for same pressure is h meter : -
9.8 * 10^4 = h*d*g
=>9.8*10^4 = h*1000*9.81
=>h = 10.0 meter
The water will rise to a height of 10.0 meter
<h3><u>Answer;</u></h3>
a) It allows electrons to flow from the anode to the cathode.
<h3><u>Explanation</u>;</h3>
- <em><u>Voltaic cell is an electrochemical cell in which a spontaneous chemical reaction produces the flow of electrons</u></em>.
- Electrons are produced by the oxidation reaction occurring at the anode. Electrons flow through the conducting wire from the anode to the cathode. At the cathode these electrons are used to reduce copper(II) ions to copper atoms.
- <em><u>A conducting wire or a wire play connects the two electrodes allowing electrons to flow from the anode to the cathode</u></em>.
Answer:
Patterns in nature are visible regularities of form found in the natural world. These patterns recur in different contexts and can sometimes be modelled mathematically. Natural patterns include symmetries, trees, spirals, meanders, waves, foams, tessellations, cracks and stripes
