Ant Nest (again) in Mangosteen Sepal

Today my Mom bought a bag of Mangosteen and found a nest of Black Ants on one of the fruit sepals. We shooed away the nannies and kidnapped the eggs and pupae (maybe).  

We saw them under the digital microscope and this is what we saw:

The eggs on the sepal. And perhaps a pupae?

A stuck ant with an egg on its antennae.

Trying to run away.

The crushed dead ants on the sepal.

Hydrogen

I learned about Hydrogen in my Science chemistry, it's an Alkali Metal too. I'm curious about it because there's an equation which is: metal + water = metal hydroxide + hydrogen. The metal can be one of the Alkali metal. For example, the metal is Sodium, so the equation becomes Sodium + water = Sodium hydroxide + hydrogen.

Hydrogen is here in the Periodic Table:

Hydrogen can be found in the sun, plants and sugar, blowtorches, water, etc. They can be either useful, and dangerous at the same time. 

The uses:

- As our body are mostly made out of water, we need Hydrogen (water/ H2O) to build energy in us.

- Transportation: It can be used as fuel, because it has a quick-burn character.

In the early 1900s, the LZ 129 Hidenburg, a hydrogen-filled passenger airship caught on fire due to the hydrogen, and crashed, killing 35 of the 97 people aboard and one ground crew member.

That's why we have to be careful in using Hydrogen as fuel.

Chinese New Year is Family Time

Today, I went to visit my Mom's aunt for Chinese New Year celebration with many of my Mom's family, then we went for late lunch in Manhattan Hotel, Jakarta.

Potassium

I learned about Chemistry in Science several weeks ago. And I read that Potassium fizzes and gives off so much heat, it catches fire.
I want to deepen what I had learned about it. Potassium is an Alkali Metal, and is an Element. They can be found in fireworks, the Crust of the Earth, the oceans, fertilizer, bananas, some other plants and fruit. Pottasium can burst, that's why they're used in making fireworks. All Potassium deposits are found in marine deposits.

Potassium can be used for:

1. Our body: it helps to build proteins, build muscle, and control the electrical activity of the heart.

If we have Potassium deficiency, we could have weak muscles, abnormal heart rhythms, and a slight rise in blood pressure. It's called hypokalemia.

If we have too much Potassium in our body, we could have abnormal heart rhythms, or heart issues.

2. Biology: They are vital to plants in photosynthesis process.  Its essential role is for regulating leaf stomata and controlling water use. For animals, they're mostly used in animal foods. It maintains salt balance between cells and body fluids.

The letter K represents Kalium in the Periodic Table.

Kalium is Potassium in Latin, but to make it easier for English speakers, it's changed to Potassium.

3. Fireworks and smoke bombs are made out mostly of Potassium. Smoke bombs can be used to mark a helicopter's landing, playing, making a dramatic scene/photo, etc.
