Explanation:
The Diabetes mellitus, commonly known as diabetes, is a metabolic disease that causes high blood sugar. In diabetes, your body either doesn't make enough insulin or can't effectively use the insulin it does make.
there are two types of diabetes
Type 1 is where your pancreas just don't make insulin but In Type 2 diabetes (adult onset diabetes), the pancreas makes insulin, but either the liver, muscle etc cells lose insulin receptor on its membrane or insulin just doesnt work properly

M+ is an unknown metal cation with a plus one charge. As it dissolves the chloride of the unknown metal, MCL, in enough water to make 100 mL of solution. The student the next is a solution with excess AgNO3 solution, causing a GCL to precipitate. The student collects a precipitate by filtration
Answers
The question is incomplete; the complete question is;
M+ is an unknown metal cation with a +1 charge. A student dissolves the chloride of the
unknown metal, MCl, in enough water to make 100.0 mL of solution. The student then mixes the
solution with excess AgNO3 solution, causing AgCl to precipitate.
The student collects the precipitate by filtration, dries it, and records the data shown
below. (The molar mass of AgCl is 143 g/mol.)
Mass of unknown chloride, MCl 0.74 g
Mass of filter paper 0.80 g
Mass of filter paper plus AgCl precipitate 2.23 g
1. What is the identity of the metal chloride?
(A) NaCl
(B) KCl
(C) CuCl
(D) LiCl
Answer:
KCl
Explanation:
Mass of paper= 0.80 g
Mass of paper and AgCl=2.23
Hence mass AgCl = 2.23 - 0.80 = 1.43g AgCl
Number of moles of AgCl= 1.43g AgCl / 143g/mol AgCl = 0.01 moles AgCl
Since Ag+ and Cl- are in a mole ratio of 1:1 so:
number moles Ag+ = number moles Cl-,
Thus Ag+ has 0.01 moles and Cl- has 0.01 moles
- MCl is also in a 1:1 ratio
Hence;
number of moles of moles Cl- =number of moles of moles M+ = 0.01 moles of M+ and Cl-
Thus;
0.01 Cl- = x/35.45 = 0.3545g of Cl-
mass of MCl = 0.74g
Mass of M+ =0.74g MCl - 0.3545g Cl- = 0.3955g of M+
Number of moles of M+ =0.3955g M+/x =0.010 mol M+
x= 39.55g of M+
K+ has a molar mass of approximately 39.10
Hence KCl is the answer

Mr. Smith wanted to see if the color of light shined on a plant had an effect on the number of leaves it had. He gathered 2 groups of the same species of plants, gave them the same amount of water, and did the test for the same amount of time. On one group of plants he used white light. For the second group he changed the light color to red.
Answers
Answer:
This question is asking to identify the following variables in the question;
Independent variable: COLOR OF LIGHT
Dependent variable: NUMBER OF LEAVES OF THE PLANT.
Constant: SAME SPECIES OF PLANT, SAME AMOUNT OF WATER
Explanation:
Independent variable is the variable that is changed or manipulated by the experimenter in an experiment. In this experiment, the COLOR OF LIGHT is the independent variable because it is the variable that was changed
The dependent variable is the variable that is measured in an experiment or the variable that responds to the changes made to the independent variable. In this experiment, the dependent variable is the NUMBER OF LEAVES OF THE PLANT.
The constant is the variable that is kept unchanged by the experimenter throughout the experiment. In this case, the SAME SPECIES OF PLANT, SAME AMOUNT OF WATER are the constants.

Which answer below correctly identifies the type of change and the explanation for the boiling of water?
physical change because even though the change caused the temperature of the water to
increase, the water's physical properties remained exactly the same
physical change because even though gas formation was observed, the water was undergoing a
state change, which means that its original properties are preserved
chemical change because gas formation was observed, which indicated that the water was
transformed into a different substance
chemical change because a temperature change was observed, which indicated that the water
was transformed into a different substance
Answers
because the molecule is changing physical states(water to steam) when a chemical change is when two molecules bind together to form a new molecule
How much energy is required to raise the temperature of a
300.0 gram block of lead from 22.3°C to 59.9°C? The specific
heat of lead is 0.129 J/gºC.
Round your answer to the nearest whole number.
Answers
Answer:
Q = 1455 J
Explanation:
Given data:
Mass of block = 300 g
Initial temperature = 22.3 °C
Final temperature = 59.9°C
Specific heat of lead = 0.129 j/g.°C
Energy required = ?
Solution:
Formula:
Q = m.c. ΔT
Q = amount of heat absorbed or released
m = mass of given substance
c = specific heat capacity of substance
ΔT = change in temperature
ΔT = T2 - T1 = 59.9°C - 22.3 °C
ΔT = 37.6 °C
Q = 300 g × 0.129 j/g.°C × 37.6 °C
Q = 1455 J
