- Elements are pure substances made of one type of atom, while compounds are pure substances made of two or more elements chemically bonded together.
- Atoms are the basic unit of elements and consist of a nucleus containing protons and neutrons surrounded by electrons in shells of different energy levels.
- Protons have a positive charge, neutrons have no charge, and electrons have a negative charge.
- Molecules are the smallest particle of a substance that contains one or more bonded atoms and has the chemical and physical properties of that substance.
- Dalton's atomic theory proposed that matter is made of atoms that cannot be created, destroyed, or converted between elements, and that compounds form from atoms combining in
Responsible Parenthood.pptx
The document discusses the Reproductive Health Law in the Philippines which guarantees universal access to contraception, sex education, and maternal care. It mandates the government to promote effective family planning methods and integrate family planning into anti-poverty programs. The law also requires employers to guarantee reproductive health rights and the government to ensure availability of related healthcare services. Responsible parenthood is defined as parents guiding and providing for their children's needs through education, nutrition, healthcare and more. Family planning allows couples to control the number, spacing and timing of children through birth control techniques.
Ideal Gas Law.pptx
The document discusses respiration and how it works. As we inhale, the diaphragm moves down which reduces pressure in the lungs and causes air to rush in. As we exhale, the diaphragm pushes up increasing pressure in the lungs and forcing the air out. Breathing involves small pressure differences between the inside and outside of the lungs. A normal breath contains about 0.21 moles of air, which is enough to sustain life.

Interactions among Living Things in Mangrove Swamps.pptx
Mangroves are plants that live in coastal tidal areas between land and sea. They are important parts of coastal ecosystems. The Philippines has over 50% of the world's mangrove species diversity. Mangroves have complex root systems and pneumatophores that allow them to live in saline waters and interact with other organisms in the mangrove swamp ecosystem through relationships like mutualism, commensalism, parasitism, competition, and predation. Mangroves are important to protect and conserve because they provide habitat for many species, contribute to marine growth, help fight climate change, stabilize coastlines, and provide resources for humans.
Proving that a Quadrilateral is a Parallelogram.pptx
A quadrilateral is a parallelogram if both pairs of its opposite sides are congruent. This is because if two triangles are congruent by CPCTC (corresponding parts of congruent triangles are congruent), then their corresponding angles and sides are also congruent. To prove opposite sides of a parallelogram are congruent, show the parallelogram has two sets of congruent triangles formed by the sides.
Environment Awareness Act and Traditional and Alternative Medicine Act.pptx
This document summarizes two national laws related to health in the Philippines:
The National Environmental Awareness and Educational Act of 2008 promotes environmental conservation and education. It integrates environmental education into school curriculums through collaboration between government agencies.
The Traditional and Alternative Medicine Act of 1997 created the Philippine Institute of Traditional and Alternative Health Care to advance and fund traditional healthcare. It aims to improve healthcare delivery and integrate traditional medicine into the national system. The law also seeks to protect indigenous communities' ownership of traditional medical knowledge and ensure compensation if outsiders use this knowledge commercially.
Maternal Health Concerns.pptx
Complications during pregnancy can affect the health of both the mother and baby. It is important for women to receive healthcare before, during, and after pregnancy to address any health problems. Before pregnancy, women should discuss their medical history and treatment with their doctor, as some medications could be harmful. During pregnancy, women may experience conditions like anemia, infections, gestational diabetes, or mental health issues. After giving birth, many women experience postpartum depression, as hormonal changes can trigger depressive symptoms. Proper healthcare at all stages of pregnancy can help ensure the health of both mother and baby.
Combined Gas Law.pptx
The document discusses the combined gas law, which incorporates Charles' law, Boyle's law, and Gay-Lussac's law. It provides the equations for each individual gas law and the combined gas law. Two examples are shown applying the combined gas law to calculate changes in pressure, temperature, and volume. The final activity asks how many 5L balloons can be filled from a starting gas quantity.
Median and Area of a Trapezoid.pptx
This document provides examples for calculating the median and area of a trapezoid. It gives two examples, the first solving for the value of x given the measurements of a trapezoid.

How to Make a Field Mandatory in Odoo 17
In Odoo, making a field required can be done through both Python code and XML views. When you set the required attribute to True in Python code, it makes the field required across all views where it's used. Conversely, when you set the required attribute in XML views, it makes the field required only in the context of that particular view.
