Answer:
C) Sugar solution is a separable mixture but steel is an inseparable mixture.
Explanation:
Sugar can be put in water then have the water dried out and there will be sugar. Metal how ever can not be a separable mixture without making it into a liquid.
Business owners must consider the products mission statement, a unique brand, the timing, the packaging, promotion, the audience.
To create a product you first need a problem then a solution. So if the problem is that water bottles aren’t holding enough water, the solution would be to create bigger yet lighter water bottles.
Let’s say you are to create a water bottle that is sturdier than others and can hold more water but weigh less. You would first consider the target audience. People that exercise and are into fitness would find the product more useful. So many making changes to the product to better fit their needs will help. Next the promotion and timing . It would be best to release the product near New Years since that’s when most people go to gyms. This will allow your product to reach a greater target audience and have more sales. Also testing your bottle to make sure it’s up to what you’re proving and so on.
Answer:
Changes in colour of litmus paper.
- Blue litmus turns red under acidic conditions.
- Red litmus turns blue under basic conditions.
Noe
PH values:-
K is acidic as pH is <7
Hence K will change the colour of blue litmus paper.
#B
Examples of substances
- K=Vinegar, Tomatoes.
- M=Milk of magnesia,Soap
PH (potential of hydrogen) is a numeric scale that is used to show the acidity or basicity of an aqueous solution. It tells how acidic or alkaline a substance is . The pH values ranges from 0 to 14, such that acidic solutions have values between 1 to 6.9 with most acidic having a pH value of 1 and those that are basic have values from 7.1 to 14, with most acidic having a value of 14. Acidic compounds contain replaceable hydrogen ions while basic compounds contain hrdroxyl ions. In this case, a coke has a pH of 3.5 (acidic) which means that it has an excess of hydrogen ions (H+) and would be called an acid.
