Answer:
A) 27.16 moles
Explanation:
According to the question, Titanium element (Ti) is the major constituent of a frame used to make a bicycle.
The titanium-frame contains 1300grams of titanium. Thus, the amount of moles in the frame can be calculated using the formula:
Number of moles = mass ÷ molar mass
Molecular weight or molar mass of Titanium= 47.87g/mol
Hence;
Number of moles= 1300/47.87
No. of moles= 27.15688
No. of moles= 27.16 moles
Note that, the less precise measurement will be used. 27.16 (4s.f) is less precise than 27 (2s.f)
The volume of a coke cup is 600 mL. What is it’s volume in cubic centimeters ?
Answer:
600 cm^3
Explanation:
The volume of a coke cup is 600 ml. So the volume in cubic centimeter is 600 cm^3
What is volume?Volume is defined as measure of 3 dimensional space occupied by a matter, substance or enclosed by a surface.
Volume is measured in cubic unit.
Cubic centimeter is commonly used as the SI unit of volume.
One cubic centimeter correspond to the volume is equal to one millimeter.
Cubic centimeter is used to measure the volume of small things.
As
1 cm^3 = 1 cm
1cm^3 = 1ml
So
600 cm^3 = 600 ml
Thus, volume of a coke cup is 600 ml. So the volume in cubic centimeter is 600 cm^3

what is a penumbra solar eclipse?
Answer:
Hi there!
Your answer is:
In a solar eclipse, we see two types of shadows. One is the "umbra" or the darkest shadow caused by the sun. It's located in the center.
The "penumbra" in a solar eclipse is the shadow that's lighter and located on the sides of the earth. Think about it like this:
The sun and earth are in line. The darkest shadow will continue in that line. That is the umbra. The penumbra continues directly on the outside of the umbra. It's lighter that the other shadow!
A penumbra solar eclipse is when the sun, moon, and earth DONT align properly. This causes a partial eclipse, not a full eclipse. A penumbra solar eclipse is a Partial solar eclipse.
Hope this helps! To be clear, none of this is copied. This is based off of my previous knowledge on the subject and interest in phenomena such as these!

Answer:
Non-metals
Explanation:
Covalent bonds usually occur between nonmetals. For example, in water (H2O) each hydrogen (H) and oxygen (O) share a pair of electrons to make a molecule of two hydrogen atoms single bonded to a single oxygen atom.
how does temperature affect density in water? explain
I said chemistry but i'm taking earth scence
Explanation: Temperature Affects Density
When the same amount of water is heated or cooled, its density changes. When the water is heated, it expands, increasing in volume. ... The warmer the water, the more space it takes up, and the lower its density.

What gas is measured in an ICE CORE and what is the correlation between that gas and temperature?
Answer:
Explanation By looking at past concentrations of greenhouse gasses in layers in ice cores, scientists can calculate how modern amounts of carbon dioxide and methane compare to those of the past, and, essentially, compare past concentrations of greenhouse gasses to temperature. Ice coring has been around since the 1950s.n:

A scientist wants to determine how temperature affects photosynthesis? He sets up a controlled experiment in which he places small plants acquired from an aquarium store into 3 separate test tubes. He pours 20 ml of cold water into one test tube, 20 mL of room temperature water into the second test tube, and 20 mL of warm water into the third test tube. He covers each test tube with a small latex balloon and measures the circumference of each balloon after 2 days. What is the test (independent0 variable?
Answer:
Independent variable: DIFFERENT TEMPERATURE
Explanation:
The independent variable of an experiment is the variable that the experimenter changes or manipulates in order to effect an outcome or response in the measured variable/dependent variable.
In this experiment, a scientist wants to determine how temperature affects photosynthesis. He sets up the experiment by adding 20ml of water at different temperatures to three test tubes. Hence, the independent or experimental variable is the DIFFERENT TEMPERATURES GIVEN TO EACH PLANTS IN THE TEST TUBE because it is what the experimenter changes in order to effect a measurable outcome i.e. oxygen released in each balloon as a result of photosynthesis, which is the dependent variable
Thus the above response is right.

mass of 42g and a
volume of 10cm". What
is the density?
Answer:
4.2g/cm^3
Explanation:
Density is a measurement of the amount of mass of a substance can fit into a space. In order to find density you can always use the formula mass/volume (often abbreviated as m/v). In this case that would be 42/10 g/cm^3 or 4.2g/cm^3
