Please help me out i don’t get this. what is the answers to 1-4.
VLD [36.1K]

Answer:

1. A circuit is a path that electricity flows along. It starts at a power source, like a battery, and flows through a wire to a light bulb or other object and back to other side of the power source.

2. A series circuit is one that has more than one resistor, but only one path through which the electricity (electrons) flows. All the components in a series circuit are connected end-to-end. A resistor in a circuit is anything that uses some of the power from the cell.

3. A parallel circuit is a circuit in which the electric current passes through two or more branches or connected parts at the same time before it combines again. Compare.

4. BOTH - 1. lightbulb 2. battery 3. switch

   SERIES- 1. Ammeter 2. voltmeter

i'm not sure about the rest sorry :(

Identify the oxidizing agent and the reducing agent for 4Li(s) + O_2 (g) to 2Li_2O(s).
Doss [256]
The reaction is:

<span>4Li(s) + O2 (g) = 2Li+  + 2O-2(s).

The oxidizing agent is the one that is being reduced which is oxygen  where the charge changed from neutral to -2 while the reducing agent is the on being oxidized which is lithium where the charge change from neutral to +1.</span>

A biochemical reaction will proceed in the direction as written if:_______a. ΔG &gt; 0.b. ΔH &gt; 0.c. ΔG = zero.d. ΔG &lt; 0.e.
garik1379 [7]

Answer:

ΔG < 0

Explanation:

The condition for spontaneity of a chemical reaction is that ∆G<0. Hence for any biochemical reaction to proceed as written, ∆G must have a negative value.

If ∆G >0, the reaction is not spontaneous and will not proceed as written. ∆G=0 means that the reaction has attained equilibrium.

Which equation agrees with the ideal gas law?
Pavel [41]

The equation for ideal gas law is written as PV = nRT.

<h3>What is Ideal gas law?</h3>

Ideal gas law states that, the volume of a given amount of gas is directly proportional to the number on moles of gas, directly proportional to the temperature and inversely proportional to the pressure.

PV = nRT

where;

  • P is pressure of the gas
  • V is volume of the gas
  • n is number of moles
  • R is ideal gas constant
  • T is temperature

Thus, the equation for ideal gas law is written as PV = nRT.
