You have decided to bake a cake. You mix all of your ingredients together to make a delicious chocolate cake. Then, you bake your cake at 350 degrees fahrenheit. You have to perform both a physical and a chemical change to bake a cake. What is the chemical change? Include at least 2 pieces of evidence or indicators to explain how you know it was a chemical change.
Answers
Answer:
A gas is evolved
The ingredients can not be recovered
Explanation:
A chemical change is one in which a new substance is formed and it is not easily reversible.
One major ingredient used in cake baking is the baking powder or baking soda.
Baking a cake can be viewed as a chemical change. This is because, when the baking powder or soda is added in the presence of yeast, carbon dioxide gas is evolved as tiny bubbles of gas which makes the cake light and fluffy. Heat is equally given off in the process. The baking powder and other cake ingredients can not be recovered, hence, we can conclusively assert that a chemical change has taken place.

How many atoms are in 0.075 mol of titanium?
O 4.5 x 1022
O 1.2 x 10-25
O 6.4 x 102
O 2.2 x 1024
Answers
Answer:
The answer is
4.5 × 10²²Explanation:
To find the number of atoms of titanium , given it's number of moles we use the formula
N = n × Lwhere n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question
n = 0.075 mol
We have
N = 0.075 × 6.02 × 10²³
We have the final answer as
4.5 × 10²²Hope this helps you

Find the speed of the ATV that goes 60 miles in 2 hours._______________________ m/hr
Answers
Given parameters:
Distance of ATV = 60miles
Time = 2hrs
Unknown:
Speed = ?
Solution:
Speed is a scalar quantity. It has magnitude but no direction. Mathematically, speed is distance divided by time.
Speed = [tex]\frac{distance}{time}[/tex]
Input the parameters;
Speed = [tex]\frac{60}{2}[/tex] = 30miles/hr
The speed of the ATV is 30miles/hr

Answers
Answer:
A lithium ion has a charge of +1.
A calcium ion has a charge of +2.
An aluminum ion has a charge of +3.
A fluorine ion has a charge of -1.
An oxygen ion has a charge of -2.
Below, the correct charges of the elements are listed;
A lithium ion has a charge of +1 A calcium ion has a charge of +2 An aluminum ion has a charge of +3 A fluorine ion has a charge of -1 An oxygen ion has a charge of -2The ionic or electrical charge of an element is the new state the element acquires because of losing or gaining an electron.
When elements lose their electrons, they tend to attain a positive charge and when they gain an electron, they tend to acquire a negative charge. To easily identify the charge of the ions, the periodic table should be used.
Elements (metals) found on the left side of the periodic table tend to have a positive charge while elements (non-metals) on the right side of the table usually assume a negative charge.

Using the enlarged metric ruler segment shown below, what is the length of the

Answers
Answer:
1.8 cm
Explanation:
To measure length, use a metric ruler. It is separated into centimeter-sized units. One centimeter is represented by each number on the ruler. The longest mark is the centimeter.
What is the enlarged metric ruler segment?A metric scale is used to quantify traits or variables. Interval scales, ratio scales, and absolute scales are all grouped under the phrase “metric scale.”
The majority of statistical calculations and comparisons are possible with quantitative numerical values.
To the nearest tenth of a centimeter (0.1 cm), a metric ruler, for instance, may measure length. Using a separate metric ruler, you can measure lengths to the nearest 0.05 centimeters (0.05 cm).
The measurement with the lowest degree of uncertainty (0.05 cm) is more accurate.
Therefore, 1.8 cm is the length of the blue line in centimeters.

Typically, water runs through the baseboard copper tubing and, therefore, fresh hot water is constantly running through the piping. However, consider a pipe where water was allowed to sit in the pipe. The hot water cools as it sits in the pipe. What is the temprature change, (ΔT), of the water if 210.0 g of water sat in the copper pipe from part A, releasing 3178 J of energy to the pipe? The specific heat of water is 4.184 (J/g)⋅∘C.
Answers
Answer:
-3.617 °C
Explanation:
Step 1: Given data
Mass of water (m): 210.0 g
Energy released in the form of heat (Q): -3178 J (the minus sign corresponds to energy being released)
Specific heat of water (c): 4.184 J/g.°C
Temperature change (ΔT): ?
Step 2: Calculate the temperature change
We will use the following expression.
Q = c × m × ΔT
-3178 J = 4.184 J/g.°C × 210.0 g × ΔT
ΔT = -3.617 °C
8.3 kg, 1.7 Kg/cm3
-> ? cm3
Answers
Answer:
4.9 cm³
Explanation:
Given data:
Mass value = 8.3 kg
Density = 1.7 kg/cm³
Volume = ?
Solution;
In given question from the units we got to know that the mass and density value is given and we have to calculate the volume.
Thus, we will apply density formula.
Density = mass/ volume
d = m/v
1.7 kg/cm³ = 8.3 kg/ v
v = 8.3 kg/ 1.7 kg/cm³
v = 4.9 cm³
Thus, the volume is 4.9 cm³.
